Jackets insulated with synthetic material stand apart from down for one very important reason: they keep you warm even if they get wet (delicate down loses all insulating properties if it gets wet). Knowing that, this style can be the better choice for those who live in a humid, rainy climate, or if you like to sweat it out on the trails, and might even end up being one of the most worn items in your closet, taking you from a sunrise hike to a casual stroll around town for coffee afterward.
The best insulated jacket we have worn is the Arc'teryx Atom Hoody. Keeping its top spot over the years, this jacket is warmer than it looks, but maintains great breathability, making it incredibly capable for faster-paced activities. We also love the fit, and feel just as comfortable wearing it with jeans and a sweater as with a pair of hiking pants.
For a low price and ultimate cozy features that will keep you warm while bouncing around town running errands, window shopping, or taking the dog for a walk, look to the Columbia Heavenly Hoody. It has a comfortable, casual fit while staying much more affordable than other jackets.
We have been testing synthetic insulated jackets for well over 10 years, and have worn more than 60 different models in that time. In each round of testing, we wear these jackets over the course of a few months, focusing on key components like warmth and comfort, both in the mountains and around town.

If we're being honest, we have a hard time taking the Arc'teryx Atom Hoody off to make time to test other jackets. It's our go-to for chilly mornings, cold cardio, and just about any outing or activity. The Atom feels and fits differently than most jackets we tested. The cut has been updated, and Arc'teryx managed to make it fit even better: Stretch-knit cuffs keep out cold breezes and moisture, and the high collar blocks wind and precipitation. Breathable side panels helped to regulate body temperature when we were putting in the effort, but the insulation on the front and back of the torso kept us warmer than the slim cut would imply. This is great as a standalone jacket, but it's also the perfect layering piece. We had no problem wearing bulky base layers underneath or throwing a shell over top. “I love wearing it on its own in mild to cold weather or as part of a layering system in frigid temps,” one tester said. “In fact, I find it hard to ever take this jacket off.”
The Atom is lightweight and compressible, and fends off the wind quite well, especially with the updated exterior fabric. But it's not the warmest jacket we tested, and it does not have the best water resistance. However, we kind of like this, since it makes it more breathable and versatile overall. We were also able to use it more, stretching its wear time into late spring and early fall. If you're looking for something warmer, check out the Patagonia DAS Light or the Columbia Heavenly.
The Columbia Heavenly Hoody is a flattering, casual hooded jacket with cozy features. The soft fleece lining inside the hood feels deluxe when the temps drop, and the extended stretch-knit cuffs with thumbholes are both soft and protective. The outer shell handily cuts the wind and repels rain and snow, and we had plenty of room underneath for layering when we needed to really bundle up. We also loved the look of this coat, which sports an understated style that's equally at home on a morning hike or out to dinner. To top it off, it's more affordable than many other options and has features usually only found on pricier jackets.
With its thick insulation and sturdier materials, the Heavenly Hoody loses some breathability and packability. It's one of the few jackets we tested that doesn't pack into its own pocket, and it's by far the heaviest jacket in our lineup, even though it isn't the warmest one. Yet we love the comfort and vibe when wearing this coat to explore a mountain town on a cold winter night. It's a high-value and stylish jacket with solid performance and a great price. If you can't swing the cost, the Outdoor Ventures is another very affordable jacket with great wind and water resistance, but admittedly less style.
The Rab Cirrus Flex is a super cozy hybrid jacket that is built with a mix of stretchy fleece panels and lofty, baffled synthetic insulation that strike a near-perfect balance between warmth, comfort, and breathability, and it does it at a much lower cost than other top jackets. Whether we were heading out for a chilly fall hike or needed a quick layer to throw on for the morning winter dog walk, this jacket quickly became one of our favorites. The fleece stretch panels run down the sides of the jacket, the bottom of the arms, and the hood. They provide both extra venting and a lot more mobility and comfort to the jacket, thanks to the four-way stretch. We appreciated the cozy touch added by the fleece backing around the chin guard, and ample storage from generous hand pockets and interior pockets.
While the stretch panels provide a lot of benefits, they have their trade-offs. The fleece material allows cold wind gusts to sneak through more when compared to the material of the main body, and it also isn't water-resistant. It can also be a pain to pull on over a thick, chunky sweater. Our primary gripe with this jacket is that it could use more pockets. “While it has large hand pockets, I really love a zippered chest pocket to keep my phone and a key safely tucked away,” noted our lead tester. Minor grievances aside, we love wearing this jacket across a range of climates and activities. This is a great active insulator, but if you're after superior weather-proofing and warmth, check out the Patagonia DAS Light. If you like the stretch and comfort, and want even more breathability for winter runs, snowshoe hikes, or ski-skate sessions, the Cotopaxi Pacaya 2.0 Hooded is worth checking out.

The Patagonia DAS Light Hoody remains a standout year after year among insulated jackets. Its seamless, baffle-free construction and spacious fit through the arms and torso allow for effortless layering and movement. The hood is impressively roomy and adjustable, easily accommodating a helmet or beanie without inhibiting motion. The outer fabric sheds rain, sleet, and snow better than most other jackets in the lineup and effectively seals out even high, snow-driven north winds. Packed with lofty Plumafill insulation, it delivers exceptional warmth while compressing down to the size of a one-liter bottle, rivaling the packability of down. “I especially love the long cut and hem adjustability, which helps keep my backside warm,” our lead reviewer stated. Designed with alpine adventures in mind, it's a versatile piece built for the mountains.
The Das consistently outperforms every other jacket in our lineup, but it also out-prices them too. And as much as we love this jacket, we admit that the advanced performance isn't necessary if you just want something to keep you warm around town; it might not be worth the cost for every user. And despite all the many wonderful attributes, the DAS Light has some limitations. Its thin Pertex Quantum outer fabric is on the delicate side and prone to damage. One of our testers noted, “I sadly sliced the exterior on a sharp snowboard edge”. Still, the DAS Light is an excellent choice if you need the warmest thing out there to protect you from heavy wet snow and blustery winds. The Rab Xenair Alpine is another excellent option, particularly for cold, wet conditions and technical pursuits.

How We Tested
Over the last decade, we have tested over 100 insulated jackets to find the best of the best to bring to you. After sifting through reviews and specifications, we selected the most promising jackets. We purchase each one anonymously at retail cost. Once we have our selection in hand, we test them head to head, seeking out their limitations in harsh weather. We also judged their effectiveness for our day-to-day routines, like walking the dog at sunrise or chilly nights out with friends. We zipped into each jacket for many cumulative hours. Ideally, each jacket gets tested in multiple climates, in a range of conditions, and for many activities to determine where it shines. We also put each jacket through objective tests in the lab, weighing them, packing them, checking their wind resistance, and examining their water repellency. For more information on our tests, take a look at our full How We Test article.
Our women's insulated jacket testing is divided into five rating metrics:
Warmth (25% of total score weighting)
Comfort (25% weighting)
Weather Resistance (20% weighting)
Portability (15% weighting)
Everyday Versatility (15% weighting)

Why Trust GearLab
This review is headed by Kaylee Walden. Kaylee is an AMGA-Certified Ski Guide and expedition guide who spends her year following the snow to mountainous and glaciated places. That predisposition to chase winter has her often reaching for insulated jackets to keep warm and dry year-round. She finds synthetic insulated jackets especially helpful when guiding helicopter skiing in Alaska, where conditions are often both cold and wet.
We tested synthetic insulated jackets in all kinds of conditions.
Analysis and Test Results
Our selection ranges from heavier options for serious weather to featherweight, packable ones designed for cardio and travel convenience. All are subjected to an array of objective tests to measure performance in five mutually exclusive metrics: Warmth, comfort, weather resistance, packability, and everyday versatility. Though their overall scores show how they compare, we will dive into the specific metric performances of this lineup. Some jackets are good across the board, whereas others are more specialized to perform highly in one metric.
Worse Value
Better Value
What's the Best Value?
It's an inescapable reality: Good outerwear often comes with a high price tag. We place performance above all else, but we're particularly intrigued by products that also offer a solid value-to-functionality ratio. For winter activity use, we loved the Rab Cirrus Flex, made with breathable panels and lofty synthetic insulation. It offers performance comparable to down jackets that are twice as expensive. The Columbia Heavenly is an attainably priced, stylish jacket that's much less packable, but full of extra-cozy features we love for keeping warm around town.
We especially appreciate affordable jackets that perform well.
The highly affordable Outdoor Ventures hooded jacket impressed us with how well it can repel moisture and pack effectively into its own pocket for on-the-go use. This jacket is a good choice for those who may not need an insulated jacket every day, for ever-growing teens, and for those who are seeking value over performance.
Keep an eye out for price cuts on last year's colors or deals at the end of the winter season. This can be the most cost-effective time of year to buy a new insulated jacket at a fraction of the price.
Warmth
When assessing warmth, we make it a point to test each jacket in the harshest conditions we can find: Ideally wet and below freezing. We evaluate how well each jacket maintains warmth both during activities and while standing still. Insulation loft, weight and placement, along with the outer shell's performance, often play the most significant roles. But, little design details can also have a major impact. We pay close attention to features that help keep heat in, such as adjustable hoods, snug cuffs, and extended cuts that provide full coverage in brutal conditions.
The warmest insulated jacket we tested is the Patagonia DAS Light Hoody, with loft comparable to premium down options. Its continuous, baffle-free Pertex Quantum shell traps warm air inside, keeping you comfortable in the cold. It's cut long in the torso and sleeves, and that extra coverage means extra warmth. It's especially impressive considering the low overall weight of this jacket at just 11 ounces, packing a high warmth-to-weight ratio. That makes the DAS an excellent option for outdoor adventures where both warmth and weight matter. Another toasty option is the Columbia Heavenly Hoody. While less lofty than the DAS, this coat is lined with Columbia's Omni-Heat fabric to reflect your body heat back at you and has an extra-cozy faux fur-lined hood. This jacket is perfect for cold days around town, and kept comfortable during errands on below-freezing days.

Another impressively warm option is the Rab Xenair, which packs a lot of loft into a malleable, weather-protective package. Not only is the Xenair lofty, but it also features a Pertex Quantum exterior that helps it block wind and water surprisingly well for the soft feel. The hem of the Xenair provided full backside coverage for even our curvier testers, and the cuffs are among the few in the test with velcro closures to seal out gusts. However, despite all of these positives, the Xenair has an oversized fit that verges on too baggy, and we would suggest sizing down.

We're consistently impressed by the Arc'teryx Atom. It's highly breathable yet still warm thanks to its baffle-free construction, which offers no weak points for wind to get through. The North Face Casaval and the Rab Cirrus are also surprisingly warm despite their breathable panels, thanks to their lofty synthetic insulation. The lightest jacket of the test, the Patagonia Micro Puff provides pretty remarkable warmth considering it only weighs 8.2 ounces, perfect for hiking, climbing or backpacking when weight matters.

Comfort
When assessing the overall comfort of each jacket, we're seeking uninhibited movement and extra cozy elements like fleece lining, non-restrictive hoods, and adjustment cords that are easy enough to use without taking off your gloves. We also consider how well you can layer underneath and over the jacket based on its fit, construction, and mobility. We consider pockets, their placement, their utility, and how many there are. Lastly, we examine the fit of each jacket, how well it fits a range of body types, and how the jacket's material feels.
The Arc'teryx Atom is incredibly comfortable. Ditching the classic swishy exterior and adding stretch-knit cuffs increases the sweatshirt-like feel of this moderately stretchy jacket, as well as its ability to be very easily layered both over and under other garments. The Columbia Heavenly Hoody is full of cozy features that many of the more technically focused models in our lineup don't have. The wrist-warming cuffs with thumbholes and the soft, fuzzy hood lining and chin backer add warmth and make us feel all snuggly inside this jacket. The North Face Casaval also fits incredibly well with stretch panels to keep the jacket snugly in place while also increasing mobility in the shoulders.

In a similar vein, the slightly boxy Cotopaxi Pacaya is a joy to wear and move in. It has a soft exterior with stretchy, breathable fleece panels that allow for easy movement. Same goes for the Rab Cirrus: The hybrid design has strategically-placed, stretchy fleece panels that make the jacket more comfortable to move in, and more accommodating to different layers beneath. The Patagonia DAS Light is another super comfortable jacket, though in a different way. It's highly lofty, delightfully puffy, and has a generous silhouette that allows for unencumbered movement. A longer torso and sleeves add to its coziness, while articulated raglan sleeves allow for overhead movement without exposing your midriff.

Weather Resistance
To assess weather resistance, we went outside when Mother Nature offered soul-crushing weather, and went hiking, skiing, and even just stood out in the elements. If the forecast called for a wintry mix, then we were out in it. We then brought our testing indoors to objectively compare the jacket's water and wind resistance. We tested them in front of high-powered fans to find weak areas, and sprayed, poured, and rubbed water into the fabric of each jacket. Though none of these jackets are meant to be a standalone layer against all-day rain, some of them did a pretty solid job keeping us dry. And though we don't recommend getting them soaked, that is one of the biggest benefits of synthetic insulation over down: It will continue to insulate even when wet.
Water Repellency
An insulated jacket does not serve as a substitute for a rain jacket or hardshell, but many of the jackets that we review are treated with a DWR (Durable Water Repellent) finish. Ideally, you want your insulated jacket to be able to seal out some light precipitation in a pinch.
When it comes to both wind and rain, the Patagonia DAS Light comes out on top. This insulated jacket is entirely baffle-free, eliminating the lines of weakness that other jackets have. Over time, the stitching to create baffles nearly always becomes minute holes that let wind and water seep in. Not so with the DAS Light. We wore this coat all day skiing while wet, heavy snow pelted us nonstop, and we never saw a shred of evidence that any of the water made it through to the insulation. Nearly as impressive is the Columbia Heavenly Hoody. The Storm-Lite DP II polyester exterior of this jacket repelled wind with ease and lasted for a long time against a downpour. Even as the fabric eventually allowed water to soak in, it never reached our inner layers, ensuring we remained toasty warm within.

The Arc'teryx Atom is another baffle-less model we tested. Though this jacket is much thinner than other top-scoring models, that lack of baffling proved its worth when pitted against both wind and water. Snug cuffs keep your arms sealed from the cold, while a dual-adjusted hem easily closes the jacket against any weather. The Patagonia Micro Puff and Patagonia Nano Puff both also had great performance in repelling moisture, both in the lab and in stormy conditions.
When a cold fall breeze kicked up, or an unexpected cloudburst rolled through, we could trust the Nano Puff.
The affordable Outdoor Ventures was an impressive contender in this category, sealing out all of the moisture we tried to throw at it. Even when holding the arm of the jacket under running water for two minutes, we were not able to get any water to soak into the exterior fabric. This jacket also has an interior continuous layer of nylon to prevent any weak points for the wind to get in. Additionally, the hood adjustment allows you to very effectively “batten down the hatches,” as they say, and completely seal out icy gusts.

Breathability
Breathability is more important than you might think for recreating in very cold weather. If you become soaked with sweat underneath your jacket, your base layers will no longer keep you warm once you come to a stop — a recipe for potential hypothermia. We tested breathability by wearing each jacket while doing hard work and cardio activities like backcountry skiing, running, climbing, and snowshoeing. We noted how their fabrics handle excess body heat and what features they have (or lack) that make them more breathable. We took note of breathable panels and material changes that enable better breathability.
The most breathable jacket in our lineup is the Cotopaxi Pacaya. It's smartly insulated with recycled wool, which wicks moisture away from the body more effectively than synthetic fibers do. It also comes with stretchy grid-fleece panels that facilitate airflow. This jacket overall has a thin profile, lower loft than other jackets in the lineup. The looser fitting hem also helps facilitate airflow. It's also very effective as part of a cold-weather layering system. Another standout in the lineup is the Rab Cirrus, which also features stretch fleece panels in
Both the Pacaya and Cirrus have integrated fleece panels for enhanced mobility and breathability.
The Arc'teryx Atom also does a great job with breathability. Its knit side panels help offload excess body heat, and its stretch-knit cuffs ventilate and can be pulled up easily. The Atom is a great option for stop-and-go activities where you need breathability while moving, but warmth while standing still. We spent a lot of time wearing this jacket for activities like winter running and backcountry skiing, and it works amazingly for the hot-to-cold nature of both of these activities. The North Face Casaval also falls into that same camp, with a soft, malleable exterior, amazing comfort, and breathable stretch panels that help easily vent heat when working hard.
For activities on the go, the Atom is both packable and breathable.
Everyday Versatility
To evaluate versatility, we wore each jacket for a wide range of activities, as temperatures rose and fell throughout the day, and through the seasons. We paid particular attention to how easily each jacket transitioned from active outdoor use to everyday life, like hiking on a chilly morning to running errands around town, walking the dog, or heading out for dinner. Jackets that provided enough warmth for extra cold days without feeling overly hot or bulky in milder weather scored particularly well. Style played a role here, too. While highly specialized jackets can excel in the mountains, we gave higher versatility scores to models that felt equally at home on the trail as out on the town. Ultimately, the best performers were jackets we found ourselves reaching for the most, across the widest variety of conditions and activities.
The Arc'teryx Atom came out on top for versatility. We essentially live in this jacket throughout the fall and winter, and there's almost no activity in the cold that wouldn't have us reaching for this jacket. The clean style and cut also make it a great choice for casual outings around town. The relatively low profile and generous fit without being bulky make it so easy to layer below and above other jackets.
Both the Nano Puff and Atom have great versatility for use over different seasons and for all kinds of activities and settings.
The Patagonia Nano Puff is a classic insulated jacket that provides a good level of warmth for a bunch of different activities, climates and settings. Its solid water resistance make it a great choice for places like the Pacific Northwest. We always love when a puffy jacket doesn't look “out of place” with casual clothing. The Nano Puff looks just as at home at the crag as it does heading out for drinks. In a similar vein, the relaxed fit, softness and light insulation of the Cotopaxi Pacaya make it a great jacket for year round. It's so comfortable that we found ourselves reaching for it through a wide variety of weather forecasts and activities.
We're off to enjoy the cold weather in the best insulated jackets! Credit: Kaylee Walden
Other Insulated Jackets to Consider
We tested the Ortovox Swisswool Piz Boè in the past, and we loved the ultra-breathable wool insulation. A new version, the Ortovox VENET SWISSWOOL 60, was released this fall, and while we haven't had a chance to test it yet, we plan to get our hands on it for the coming winter.
The Outdoor Research Vesper Hoodie is an insulated jacket with integrated stretch in the shell material and breathable underarm panels. We are intrigued by this jacket that promises to provide warmth without bulk, and looks to provide a balance between warmth and ventilation for anyone who likes to stay active through the fall and winter.
We hope this review helps you find the jacket with the perfect balance of qualities for your needs. Credit: Kaylee Walden
Conclusion
We hope our unbiased review process and in-depth testing will help you narrow your selection to which insulated jacket is the right one for your lifestyle, favorite activities, climate, and budget.
We've continuously tested a wide range of women's jackets through the years. Most insulated jackets work at their best with a comprehensive cold weather layering system: Starting off with cozy long underwear beneath, and finishing with a hardshell jacket over the top, and a warm pair of gloves can help you get the most out of your synthetic warmth in inclement weather.
