The secret to keeping warm lies in your layers, and a fleece is a prime piece of gear for the job. We tested the fleece jackets here in a range of temperatures, while lounging at home and charging through the outdoors, to understand their warmth and breathability. We layered them over t-shirts, baselayers, under down jackets, and hard shells to see how well they insulate us in the colder months.

We've spent the last decade testing more than 170 of the best fleece jackets on the market, with our top 10 favorites in this review. Both male and female testers loved the Patagonia R1 Air Full-Zip Hoody. It has a great warmth-to-weight ratio and is breathable enough for active users.

Our female test team selected the Arc'teryx Kyanite Hoody as the overall favorite. The midweight material is cozy like your favorite sweatshirt and better at blocking wind than some of the other options.

Editors' Note: We updated this review on October 31, 2025, to add updated testing perspectives and media from the latest fleeces tested from our award-winning women's lineup.

10 Best Fleece Jackets


Best Men's Fleece


Patagonia R1 Air Full-Zip Hoody


REASONS TO BUY
Great warmth-to-weight ratio
Breathes well and packs small
REASONS TO AVOID
Not very wind-resistant
High-pile fleece collects debris

Who this is best for: The Patagonia R1 Air Hoody is an excellent addition to a cold-weather layering system. It is a breathable fleece jacket that works well during aerobic activities like climbing, hiking, or ski touring. Breathable is the keyword here, and if you're constantly on the move and looking for a lightweight layer that won't overheat, this one's for you.

Why we love it: The R1 Air works well when you're layering for a cold start. This hoody has a fantastic warmth-to-weight ratio and packs down small, making it easy to stash in your bag when it's time to shed. The recycled polyester fabric feels soft and moves moisture effectively when you start to sweat. One of our testers said, “I love the highly breathable design, which is ideal for active adventure. It's my go-to for heavy exertion during outdoor adventures.”

Should you buy it? For active movement in cold weather, we think this is best men's fleece out there. However, the R1 Air isn't perfect for every use case. It doesn't offer much wind resistance, and if you're standing still in cold or gusty weather, you'll want to layer a windbreaker or insulated jacket on top. Those looking for a super warm layer for chilly nights outdoors should check out a thicker option, like The North Face Denali.

Weight: 12.8 ounces | Type: Lightweight

While no jacket is perfect, the Patagonia R1 Air comes pretty close. It's the perfect warmth and weight to wear almost every day, whether on its own or under a heavier layer. It is one of our most reached-for fleeces.

Best Women's Fleece


Arc'teryx Kyanite Hoody - Women's


REASONS TO BUY
Supremely comfortable
Warm and wind-resistant
Stylish
REASONS TO AVOID
Less breathable
Expensive

Who this is best for: If you love comfort, the Arc'teryx Kyanite Hoody should be on your list. This sweatshirt-like layer offers the wicking ability of a technical fleece without eliminating that soft and cozy feel next to skin. It's an ideal option for women who prioritize being comfy and and warm during low-output activities or chilly days outside. The high-quality design is also clearly built to last. If you don't mind paying more for a long-lasting piece of gear, we highly recommend the Kyanite for it's all around comfort and warmth.

Why we love it: Arc'teryx certainly nailed the design of this fleece — it essentially combines performance fleece with the ease and comfort of your favorite sweatshirt. Its fabric is soft and stretchy, and it works great as a standalone jacket or sandwiched in a layered system. “There's a generous cut through the shoulders, arms, and torso, so I never felt restricted or limited in range of motion, even when wearing it while rock climbing or trail running,” says our lead tester, Trish Matheny. Arc'teryx thought of everything, from articulated patterning to flatlock seams that won't bother you while carrying a backpack. The smooth outer fabric also resists dirt and debris, which keeps you looking fresh and clean, even after enduring multiple cycles of wear, wash, repeat.

Should you buy it? If you love the plush feeling of a warm and cozy sweatshirt, this is that on steroids. If you're not the type to have a lot of downtime when you head outdoors, the Kyanite Hoody might be a bit too warm, and doesn't have the same level of breathability as some lighter-weight options. It isn't our first choice for hard-charging pursuits. The main zipper is a weak point in a stiff breeze, but that doesn't outweigh the higher overall warmth rating of the material. Lastly, we can't deny that this high-performing jacket is pricey; however, when the temperatures drop, it is the fleece we find ourselves reaching for the most.

Weight: 13.5 ounces | Type: Midweight

Most Versatile Men's Option


Arc'teryx Kyanite Hoody


REASONS TO BUY
Super comfortable
Stylish and versatile
Good balance of warmth and breathability
REASONS TO AVOID
Fabric pills
Baggier fit
Lacks a chest pocket

Who this is best for: The Arc'teryx Kyanite Hoody is ideal for anyone who wants one fleece that can handle both outdoor adventures and everyday life. Whether you're climbing, hiking, layering it for skiing, or just heading out to walk the dog or grab groceries, this piece fits right in. Our testers never got tired of wearing it. It's a solid choice if you value comfort and versatility and want something that looks stylish, too.

Why we love it: The special part about this hoody is the fabric. It has a super soft feel, a relaxed fit, and offers a near-perfect balance of warmth and breathability. We really appreciate the stretch fabric and felt that the jacket moved easily with us. One tester said, “I love the feeling of the material against the skin. It's breathable yet still warm. I could wear this all day, whether I'm out on the trail or just lounging at home.”

Should you buy it? For a warm fleece that feels great and looks good whether you're out in nature or downtown, the Arc'teryx Kyanite is one of our aboslute favorites. However, it does have some drawbacks. It pills slightly after just a couple of weeks of wear, which is disappointing to see in such a pricey product. The fit is a little on the baggy side on our male tester, and while it has two zippered hand pockets, he missed having chest pocket storage. The mid-weight fabric is also a bit too warm for high-output activities, but if you're looking for a cozy-sweatshirt like fleece, this is it.

Weight: 14.8 ounces | Type: Midweight

With the Arc'teryx Kyanite, you don't have to sacrifice style or function; it has best-in-class performance in both domains, but it also comes with a best-in-class price tag.

Most Versatile Women's Hoody


Patagonia R1 Air Full-Zip Hoody - Women's


REASONS TO BUY
Lightweight yet warm
Breathable and packs well
REASONS TO AVOID
Slim fitting
Wind sneaks through

Who this is best for: The Patagonia R1 Air Hoody is perfect for women who move fast and want a fleece that can keep up. If you're into activities like trail running, climbing, or hiking in chilly conditions, the R1 hoody is light, breathable, and layerable. The updated design features a more spacious fit through the length of the torso and arms, while the redesigned chest pocket is much larger and more functional. Just keep in mind it's designed for motion, not standing still in cold weather.

Why we love it: This fleece balances warmth and breathability really well for how lightweight it is. It packs down easily, feels soft against the skin, and doesn't get in your way when you're on the move. One tester shared, “I love how it keeps me warm while I'm active, and yet I never feel sweaty or restricted. It's a great performance layer.” The fitted hood offers added warmth when you need it, and the quick-dry fabric works well to wick moisture away from the skin. It also resists some outside moisture if you get caught in a light drizzle (though it's far from waterproof).

Should you buy it? If you're after a high-performance, lightweight fleece to wear while running, hiking, or any other fast-moving activity, this one's a winner. However, if you'll be standing around in the cold or wind, this isn't the best choice, as wind can sneak through easily. Testers also note that the cut is pretty slim, which might not work for all body types; curvier women may struggle to find a size that fits both their shoulders and hips.

Best Value for Men


The North Face Canyonlands Hoodie


Weight: 14.6 ounces | Type: Midweight
REASONS TO BUY
Excellent comfort
Versatile fleece option
Top-tier value
REASONS TO AVOID
Bunches in some areas
Can be harder to size

Who this is best for: The The North Face Canyonlands Hoodie is a great pick for anyone looking for a comfortable and versatile fleece that won't break the bank. It is supremely comfortable and is one of the warmer options. If you need a midweight layer that works just as well on the trail as it does at the café, this hoodie's relaxed fit yet clean aesthetic makes it easy to wear in all kinds of settings, furthering its wear time and increasing the value.

Why we love it: This fleece scored high in our heat retention test; the material is thick, warm, and soft. While a smooth exterior gives the jacket more of a polished sweatshirt-style aesthetic, the interior has a cozy feel. One reviewer explained, “I appreciate the soft, next-to-skin feel of the brushed fleece interior, and found the relaxed fit comfy enough for any activity. I've worn it hiking, around town, and to dinner parties — it's just that adaptable.”

Should you buy it? The perfect fit is highly dependent on body shape and style preferences. On our tester, the Canyonlands has a looser fit, which caused bunching around the wrists and made sizing a little tricky. If you prefer a trimmer profile, you'll want to check out other options. It's also a bit heavier, so it isn't the best choice for ultralight forays into the mountains. Still, for the price, the Canyonlands delivers impressive warmth and versatility, making it one of the best values among midweight fleeces.

Weight: 14.6 ounces | Type: Midweight

Best Value Women's Technical Fleece


REI Co-op Flash Hyperstretch- Women's


REASONS TO BUY
Relatively more affordable
Moves and breathes well
REASONS TO AVOID
Light colors are see-through
Chest pocket is lumpy

Who this is best for: The REI Co-op Flash Hyperstretch is a great fit for active folks who want a breathable, stretchy fleece and need to stay in budget. No matter your chosen sport, hiking, climbing, or any other fast-paced activity, this layer offers mobility and comfort at a price that's hard to beat. Its lightweight construction, quick-drying fabric, and easy packability make it an ideal go-to for mid- to high-intensity outings.

Why we love it: Despite its budget price tag, REI included some thoughtful features in this jacket. A chin guard, wind flap, and extended hemline (with a drawcord) all make this fleece more comfortable to wear. The generous cut in the shoulders and extra arm length help it move well during activity. One reviewer shared, “After wearing it for countless days climbing in sandy and rocky areas, I really started to appreciate the amount of stretch and breathability it had. I didn't expect this level of performance from such an affordable fleece.” It has a smooth exterior that easily brushes free from dirt and debris, and a brushed fleece interior that feels cozy against the skin.

Should you buy it? For budget-conscious adventurers seeking an active layer, this fleece stands out as a great value, and we don't think you'll be disappointed. Though it's not the warmest or most wind-resistant fleece out there, it's great for rough and tumble activities in the outdoors where you need great range of motion. If you're looking for something better at blocking the chill, a midweight style might serve you better. One other complaint about the Hyperstretch: after countless days climbing in areas with lots of sand and volcanic tuff, we couldn't help but notice permanent stains on the lighter color we tested.

Best on a Tight Budget for Men


Wrangler Authentics 1/4 Zip


REASONS TO BUY
Decent ventilation
Incredibly inexpensive
Casual style
REASONS TO AVOID
No pockets
Less warm than others

Who this is best for: The Wrangler Authentics 1/4 Zip is perfect for anyone on a tight budget who still wants a basic fleece layer for casual use or light outdoor activity. It doesn't have many high-performance features, but it does the job and comes at a fantastic price. It works best in casual outdoor settings like car camping or a morning hike before heading straight into town for a coffee.

Why we love it: This fleece has a slightly roomier cut that doesn't look overly technical. We appreciate that it feels just as appropriate at a restaurant as it does on the trail. We were also surprised by its breathability. One tester shared, “I couldn't believe how well this performed for such a low cost. It's not flashy, but I could throw it on for a quick hike or a run to the store and feel totally comfortable.”

Should you buy it? If your fleece needs are more about comfort and simplicity, the Wrangler Authentics 1/4 Zip is a solid choice, especially for the price. But if you need a fleece for technical use or cold-weather layering, this isn't it. There are also no pockets of any kind, and it's not as warm compared to some of the other (pricier) fleeces.

Best Midweight on a Budget for Women


REI Co-op Trailmade Fleece - Women's


REASONS TO BUY
Super soft fabrics
Breathable
Lightweight feel
Many large pockets
REASONS TO AVOID
Not ideal for high-output activities
Some light pilling after laundering

Who this is best for: The REI Co-op Trailmade is a solid recommendation for women who are looking for a cozy, affordable fleece that works well as a casual outer layer or as part of a layering system. Our testing team wore it during hot and cold weather, and found that it's best for shoulder-season outings or for keeping warm while resting after more intense activities like surfing. It doesn't have a lot of techy features, but if you prioritize softness, comfort, and need to stick to a budget, this mid-weight jacket is worth a look.

Why we love it: In the end, this fleece won over our team because it's just so wearable, whether you're lounging on the couch or squeezing in a hike before work. It has ultra-soft fabric and an easy stretch that never feels restrictive. It became one of our go-to jackets because it feels barely there, like a warm hug that still lets you move around easily. Plus, it has big pockets that are a dream for stashing snacks or gloves. It hits a nice balance of warmth and breathability, and its lightweight feel makes it easy to wear all day, whether you're layering up or keeping things simple.

Should you buy it? If comfort, value, and softness are top priorities, this is one of the best midweight fleeces out there at this price point. If you're looking for the warmest fleece, though, this isn't it. It's also not really breathable enough for intense, sweat-heavy activities. For that reason, we would only recommend it for moderate activities and casual wear during the spring and fall shoulder seasons.

Best Lightweight Jacket for Men


The North Face Summit Series FutureFleece Full-Zip Hoodie


REASONS TO BUY
Featherweight
Breathes very well
Great warmth for its weight
REASONS TO AVOID
Odd fit
Pricey
Some pilling

Who this is best for: The North Face FutureFleece Full Zip Hoodie is perfect for cold-weather adventurers who usually stay warm by staying in motion, but need an assist every now and then. It is a high-performance layer that won't weigh you down, and can be used as a standalone layer or in combination with a rain jacket if you need more weather protection. If you're a fast-moving hiker or climber, or you like to tackle alpine routes in chilly conditions, this lightweight fleece is a great addition to your layering system. It's also ideal for anyone who prioritizes breathability and low bulk in their gear.

Why we love it: We love how breathable and warm this jacket is, especially for its featherweight feel. One tester shared, “Even on long uphill hikes and full mountain days, I never overheated. I stayed dry, warm, and didn't feel like I was in a sweat sauna like I do in heavier fleeces.” The full-loop fabric is soft against the skin, and the chest pocket is especially useful for keeping electronics safe yet accessible, while still protecting them from the cold.

Should you buy it? The cut is made for longer, leaner bodies. If you don't fit this profile, its unusual fit may leave you in between sizes. We should also note that there are no hand pockets. Otherwise, we can't find many reasons not to recommend this jacket. It's definitely an investment piece, but if premium performance in a featherweight package is what you're after, this is one of the most impressive lightweight fleeces we've tested. It's a jacket that practically disappears in your pack, but you'll always be glad you brought it.

Best Lightweight Jacket for Women


Rab Ascendor Hoody - Women's


REASONS TO BUY
Lightweight and compressible
Incredible thermoregulation
Works well in a layering system
Versatile
REASONS TO AVOID
Not warm as a standalone jacket

Who this is best for: The Rab Ascendor Hoody Women's review is a technical mid-layer that excels in breathability, and is best for climbers, hikers, and high-output adventurers who expect to sweat. It is a perfect layering piece, and almost disappears on the body. If you're someone who spends most of your time outside wearing a harness or a pack, you likely understand the importance of a jacket that layers comfortably under all the straps and buckles and even other jackets. The Ascendor prioritizes movement and moisture regulation and feels tailor-made for alpine adventures. “When climbing in the alpine later in the season, this was the perfect layer between my sun hoody and lightweight puffy when moving for extended periods at elevation,” says lead tester Trish Matheny.

Why we love it: This fleece impressed our testing team with its lightweight feel and incredible thermoregulation. When wearing in the alpine, we were impressed by how quickly it dried at the belay, even if we overheated a little bit while climbing. It doesn't add a ton of warmth as a standalone layer, but sometimes that's exactly what you need. The helmet-compatible hood, roomy shoulders, and long cut in the arms and torso go the extra mile to make it reach-friendly (for all the climbers out there). The updated design includes two zippered pockets that are great for storing essentials; however, they are not easily accessible beneath your harness. That said, it feels at home in any technical layering system, and when not on your body, it packs down small enough that it's a no-brainer as to whether or not you should throw it in your pack.

Should you buy it? If you're looking for a fleece that shines when it comes to performance under a shell or with a harness, the Rab Ascendor is our favorite technical mid-layer. It's not intended to be your go-to fleece for lounging around or running errands. It cuts out a lot of convenience features in favor of technical performance; it's not very warm on its own, however, the updated design does include the thicker 235-weight polyester fabric throughout, and even includes zippered hand pockets in addition to a large chest pocket. If you're looking for something cozier or more versatile for around town, there are other options that offer more warmth and casual usability.

How We Tested


The first step in our testing process involves scouring the market to make sure we select the most promising fleece jackets out there and stay up to date on the latest innovations. We repeat this process anew each year, and then we test the thread out of them. They go through several months of field testing that includes running, skiing, climbing, napping, lounging – you name it. We've tested the jackets in the dry air of Colorado, Wyoming, and Nevada and in humid, coastal environments in Hawaii, Canada, and California. We also bring each option into the lab to complete repeatable, objective tests, like dousing each with water and comparing the softness and pile of each fleece.

We assess each fleece jacket's performance in 5 key metrics:
  • Warmth
  • Comfort
  • Breathability
  • Layering Ability
  • Weight

Why Trust GearLab


Our women's and men's fleece jacket testing teams are stacked with people who live outside and like to stay warm while doing it.

How to Pick the Best Fleece Jacket for You


A fleece jacket is a staple of a great layering system, but how do you know which one to grab? There are several things to keep in mind — what kind of temps you'll encounter, how likely you are to work up a sweat, and whether you need your jacket to protect you from wind or rain. You'll also want to consider materials and durability. Additional features like hoods, pockets, and thumb loops are not essential, but they can drastically increase the functionality of a piece. Lastly, fit is one of the most important considerations, and the most individual. We advise you to “try before you buy” to make sure you're getting a jacket that works for your body.

Men's Fleece Jackets


The chart below shows the overall performance scores of the best men's fleece jackets we tested. You can find more details about our testing and review process in our best men's fleece jacket review.


Women's Fleece Jackets


Our team of expert GearLab female testers put all of women's fleece jackets through a similar gauntlet of tests to comparatively assess their performances. Those final scores appear in the chart below.


What Weight of Fleece Is Best?


As a standalone layer, fleece jackets serve as excellent outerwear when temperatures are mild. When the mercury plummets, they are also fantastic layering pieces, often sandwiched between thin base layers and outer layers like rain jackets or wind breakers. Warmth varies depending on the thickness or “weight” of the material, and the right weight depends on your local climate and chosen activity.

Lightweight


REASONS TO BUY
Typically more breathable, especially if made with gridded fabric
Good for long-distance adventures where cutting ounces is important
Layer easily underneath multiple other jackets
REASONS TO AVOID
Not warm enough for solo winter use
Same price as heavier jackets

Lightweight fleeces are often thin, lightweight, and pack down small. These jackets are ideal for high-intensity activities like trail running or climbing when there is a chill in the air, but you expect to work up a sweat. They also work well as a light outer layer when temperatures hover just below t-shirt weather. If temps really dip, you'll likely want to add a windbreaker, shell jacket, or insulated coat.

Most people want a lightweight layer in anticipation of mild temps or vigorous activity; in this case, breathability can be more important than warmth. If you start to overheat during a hike or run, you'll find that your base layers quickly become wet and clammy once you cool down. Manufacturers know this, and often, lightweight fleeces are made with some sort of specialty vapor release system built into the fabric.

Midweight


REASONS TO BUY
Good balance of weight and warmth for everyday use
Can be layered both over and underneath other jackets
REASONS TO AVOID
Bulkier than lightweight fleece without necessarily being warmer
Often do not come with a hoody option

Mid-weight fleeces are thicker and heavier, and they almost always hold more heat (though the occasional lightweight fleece gives them a run for their money with high-tech insulation). The downside is that the bulk of these jackets can make them cumbersome to move in and carry around, but they are usually still compact enough to wear under a more weather-resistant outer layer.

Like lightweight fleeces, mid-weight fleeces have a better chance of breathing well than heavyweight options due to the thickness and density of the fabric, but they are slightly cozier and ideal for slower-paced adventures or everyday wear. We reach for these when heading out for meandering hikes, town tours, or relaxing around a campfire. If you want to maximize warmth but don't want to feel like the Michelin Man when you layer up, you'll be happy with a mid-weight model.

Heavyweight


REASONS TO BUY
Designed for cold winter weather
Layer well on top of other jackets
REASONS TO AVOID
Generally less breathable
Can be bulky and less packable

Heavyweight fleece jackets are the heaviest and bulkiest of the trio. They don't work well as a mid-layering piece beneath other jackets. Rather, they are meant to serve as a standalone outer layer – think big, bulky, and warm. Since they are less versatile than other options, we only recommend these for cold weather or stationary activities where sufficient insulation is critical. If there's any chance you'll work up a sweat, you won't find the breathability you need here. Their bulk also makes it less appealing to shove them in a backpack for those “just in case” moments.

When to Select a Fleece over a Down Puffy Jacket


Now that we've ironed out the pros and cons for each fleece jacket weight, we also have some suggestions for helping you layer your cold-weather kit like a pro. Our team often considers a fleece jacket at the change of the season, when it's too cold for a sun hoody and too warm for a puffy jacket. Often, active objectives will also lead us to select a fleece jacket for more protection during our pursuits, without damaging the delicate fabric of a puffy jacket. For example, when rock climbing in the alpine, we preferred a lightweight fleece jacket that provided more warmth during belays and more breathability while climbing. If the temperatures were too cold to bear with only a fleece alone, we would deploy an insulated jacket while stationary at a belay.

That said, not all fleece jackets are designed for high-output activity. If you just want to stay warm when hanging around town in the cool seasons, a midweight fleece is our choice for preserving a certain level of cozy. Some of these jackets can be easily layered on top of a base layer or beneath a puffy jacket during the coldest months of the year, making them more versatile.

Overall, a fleece jacket can provide more protection from both the cold and the terrain that you'll encounter, whether you're pursuing a high alpine objective or exploring a new trail system. For some of these endeavors, a puffy jacket is overkill, limited in breathability, and sometimes too bulky to allow freedom of movement. In many cases, puffy jackets are best suited for after your adventure rather than during, depending on your objectives.

Materials


Fleece was invented in 1981 by Polartec, then known as Malden Mills. Patagonia worked with the company to make an outdoor performance jacket that wouldn't hold as much water as traditional wool. The iconic Synchilla Snap-T fleece was first available for sale in 1985. Since then, the base insulating material has remained much the same, with different manufacturers adding their own twists to improve breathability, water resistance, etc.

Things like a hard face fabric or strategically placed panels on the chest and shoulders can be used to improve weather resistance in some jackets. Others use a fabric that is thick and dense enough on its own to stop any wind. However, you'll only get true weatherproofing by layering a fleece under waterproof or wind-resistant shells. This more comprehensive layering style puts you in the driver's seat to regulate warmth and comfort while on the go.

Today, fleece jackets are made of a blend of synthetic materials like polyester, nylon, elastane, and, less frequently, spandex. Sometimes, these materials are recycled; occasionally, they include some wool. A few companies are working to build fleece fabric in ways that reduce shedding, but with repeated washing, synthetic fibers from these jackets become microplastics that end up in our water systems. You can reduce your impact by choosing a fleece with some wool, going longer between washes, using the gentle cycle on your washing machine, or installing a microplastic filter in your washer.

Durability


Fleece tends to be a sturdy material; however, at the end of the day, it is made of plastic fibers that can melt quickly, so be careful around the campfire. Other quality points to pay attention to are zippers and seams. Additionally, thinner, lightweight fleeces made to breathe well have less fabric, and by nature, can be more prone to wear and tear.

Features To Consider


The easiest way to improve the warmth of your fleece without adding bulk is by purchasing one with a hood. If you're going to use your jacket primarily as an outer layer, it's nice to have one for unexpected encounters with chilly or windy weather. However, beware of hood overkill; if you often layer your fleece with other jackets, you probably don't need a hood on all three, so take a look at what's in your closet already.

Thumb loops are another handy feature that some of our testers can't live without. They help hold insulation and protect your hands from sun and wind exposure. While not as crucial as a hood, they can do a lot to make an outing more comfortable. We also love having an array of pockets, which are essential for keeping your hands warm and your valuables secure.

Fit


As there are many unique body types, fit is highly subjective, but there are a few universal things to look for. The torso should be long enough to still cover your belly when you raise your arms, but not so long that it gets bulky around the hips. For curvier people, especially women, it can be nice to have a wider hem so your fleece doesn't ride up. Some hemlines are a bit longer in the back, have an elasticated hem, or an adjustable cinch, all of which can improve the fit.

When testing shoulder fit, make sure you can easily reach your hands above your head. Jackets that offset standard seams (from the top of the shoulders to across your upper back) offer more room for broad-shouldered folks. Sleeve length should hit right at the wrist unless the jacket has thumb loops, in which case it should come down to your knuckles so you can use them without pulling the fabric tight across your shoulders.
