Looking for the best climbing chalk to dry out sweaty tips and improve friction? We researched over 30 different options, then settled on 10 of the best and most popular choices for inclusion in this comparative, side-by-side review. Whether you like natural chalk or appreciate drying additives, want a simple block, ball, or a big old bag, or even want a tube of liquid chalk instead, we've tested them all. Our expert testers conducted blind tests at the boulders of Bishop and in the gym, allowing experienced lifers as well as fresh beginners to sample the different varieties and offer their opinions without brand bias. We graded each choice for how well it covers your hands, how much it enhances friction, the mess it makes, and of course, the all-important dirtbag consideration — how much do you get for the money? Read on below for our favorites and recommendations.
Using chalk can inspire more confidence on the rock — and so can using the right gear. Our dedicated climbing testers have spent a lot of hours getting outside (and hitting the gym, too!) to find the best climbing harness, best climbing shoes, and top-ranked climbing ropes. If you're looking to train hard, we've outlined the best hangboards on the market, too.
Editor's Note: We updated this review on February 29, 2024, to remove some discontinued chalks and to share alternative recommendations to our top award picks.
Black Diamond White Gold offers the perfect combination of value and performance. Whether you prefer your chalk in a fine powder for thick, cakey coverage or full of hefty chunks, you can have it all in one 300-gram bag (100-gram and 200-gram bags are also available). From the dry air of the high desert to humid climbing gyms in the Southeast US, White Gold consistently delivered the extra friction and confidence we needed to focus and climb hard.
The BD White Gold produces a lot of dust and is easily spilled, as is the case with all loose climbing chalk. We found the Friction Labs Gorilla Grip is easier to manage with its resealable coffee bag style packaging with a narrow opening, but it will cost you more than double the price. We recommend pairing White Gold with a refillable chalk ball if you want to reduce dust inside your climbing gym while also preventing spills.
Pinching pennies and stretching dollars so you can afford a rack of cams or a massive new crash pad? Metolius Super Chalk is the best way to keep costs down and your chalk bag full. This is the least expensive option we tested, and while some testers preferred Friction Labs Gorilla Grip or BD White Gold, they couldn't discern a big difference in performance in our blind testing. Each bag includes chalk chunks and fine powder and seems heavier on the powder than the competition, creating more dust and making it easier to load into a refillable chalk ball. Large chalk chunks must be ground down before they can fit in chalk balls, which can be messy. Super Chalk was one of the first chalks that introduced an antiperspirant additive to keep fingers and palms from getting sweaty. This feature can be love/hate depending on whether you have super sweaty or overly dry skin.
Anecdotally, our testers described this chalk as feeling silky, fine, and more prone to caking up than other brands. If you like a ton of chalk on your hands, you may prefer Super Chalk. During our climbing chalk testing, we learned first-hand that there is such a thing as “too much chalk” on your hands and the climbing holds, which can cause holds to feel slippery if not properly brushed. Still, for bargain hunters and just about everyone else, Metolius Super Chalk gets it done for a low price. If you're looking for slightly better friction and feel, the Black Diamond White Gold performed better in this metric.
Trango Gunpowder (for your guns, get it?) is a fine cut entry into the chalk world. As brands strive to make their mark on the chalk market, their main way to distinguish themselves is through packaging and chalk texture. Gunpowder is consistently fine, much finer than FrictionLabs Unicorn Dust, but not powdery fine like the Bison Designs Competition Chalk. The result is a chalk that provides good coverage every time you dip your hands in your chalk bag at a great price, all in a container that won't leave a big chalky mess inside your backpack.
The drawback to fine chalk like this is it lacks bigger chunks for making tick marks and tends to become aerosolized. Chunkier chalk blends will always become finer as they get crushed down over time in your chalk bag, but it won't cover your hands as well (initially) as finer chalks do. In the gym, dust wafting from your chalk bag is generally frowned upon. However, if you're lucky enough to do most of your climbing outdoors, and you're a stickler for fine texture, Trango Gunpowder is an excellent pick.
Unusable if you have cuts or abrasions on your hands
Liquid chalk is not for everyone
For climbers looking for a little something extra to up their game, Mammut Liquid Chalk can make greasy hands feel drier than dry. A teaspoon-sized dollop of liquid chalk completely coats both of your hands in a bright white layer of chalk once it dries. We find that a base layer of liquid chalk can help loose chalk adhere to our hands better throughout a climbing session, causing us to chalk up less.
The “liquid” part of liquid chalk is alcohol, which evaporates quickly, but if your battered hands are covered with cuts and gobies, then you shouldn't use liquid chalk. Sure, it sterilizes, but it also stings, and rubbing fine grains of chalk into your wounds doesn't exactly promote healing. Mammut's Liquid Chalk is a much better value than some other contenders we tested. Another low-cost option is the Trango Gunpowder. It performed equally well in our mess test and has a fine texture for those who prefer loose versus liquid chalk.
To test and compare these various types of chalk, we bought a pile of each and spent three blissful months climbing in Bishop, California's many surrounding climbing areas. When the weather wasn't so nice, and to be sure we accounted for the particular type of shmarm found only on old polished holds, we also tested each of these options in the gym. To eliminate our inherent user biases, we also tested chalk blind and recruited faithful test rats to use our chalk for free in exchange for their opinions. Almost everyone involved in this test had their convictions shaken, and you can consider this the best crowd-sourced chalk review on the planet.
Our testing of climbing chalk is divided across four rating metrics:
Friction & Overall Feel (25% of overall score weighting)
Coverage (25% weighting)
Mess (25% weighting)
Value (25% weighting)
Our lead tester is Matt Bento, a climber for over a decade. He's been fully immersed in all disciplines of rock climbing at some point or another, spending summers scrambling around the High Sierra while working for Yosemite Search and Rescue and winters living in his van at Hueco Tanks and in Bishop. He's used about every chalk product out there and came to this review with some strong opinions (Frank Endo was his favorite chalk) that were quickly deconstructed after he failed to identify his favorite chalk during our blind testing. Joining him is Andy Wellman, another lifelong climber and former guidebook publisher who has spent most of his life bumming between different climbing areas. He came to this review a firm Super Chalk fan, but like Matt, found it very difficult to choose his favorite out of the blind test lineup.
Analysis and Test Results
Comparing chalk objectively is no easy task, as many variables affect how sticky the rock feels and how confident you feel while climbing. Many of the subtle differences in chalk brands appeal to certain climbers, but regarding performance, we noticed only slight variations from brand to brand. To cover all angles of the chalk world, we compared liquid chalk to loose chalk and chalk balls, which occasionally gets us into “apples to oranges” territory. We feel, however, that this broad approach helped us discover more than we ever knew about climbing chalk.
We chose four metrics to see how these chalk products measure up and help you learn what chalk products are most appropriate for your needs; friction and overall feel, coverage, mess, and value. While Black Diamond White Gold came out as our favorite chalk and a top scorer, other brands may be a better choice for you, depending on your skin and where you climb.
Friction & Overall Feel
As much as we try to keep our testing standardized and as “scientific” as possible, we realize that friction and feel from chalk to chalk is subjective. Some of our testers have dry skin and only need to use small amounts of chalk, while others have self-described “pizza hands” that always glisten with sweat, leaving dark grease stains on the climbing holds. To add objectivity to our testing process, we committed to a blind chalk test. We put the chalks into numbered bags and had our testers hanging from the same sloping holds in the gym and provide feedback about each chalk. They also tried to guess which chalk was from each brand based on their past experiences. More often than not, their guesses were incorrect. This doesn't mean that all climbing chalk is the same; it means the differences between each brand are subtle.
For dedicated climbers who obsessively file their calluses and never eat cookies, chalk is one more controllable variable in their relentless pursuit of climbing aestheticism. The average climber is less likely to notice if Brand X makes the second right-hand crimp on Junior's Achievement feel schmarmy after 10 am, and will likely be satisfied with the increased friction performance from any climbing chalk.
Our objective conclusions pertain to the texture of each chalk. In general, finer more powdery textured chalk, like Metolius Super Chalk, sticks to our hands better, and it's easier to maintain a thick layer of chalk on our fingers. However, the finer chalk tends to cake up on holds, eventually causing them to feel slippery if they aren't brushed often. Bison Designs Competition Chalk is so powdery that it feels almost like flour and wafts out of our chalk bags with the slightest breeze. Chalk that feels crunchier and stays in larger chunks feels more confidence-inspiring to some of our testers since it leaves a thinner layer of chalk that doesn't feel cakey. Friction Labs Gorilla Grip consistently felt the most grippy, with Black Diamond White Gold coming in second. Frank Endo Gym Block Chalk starts out as chunky as you like and slowly breaks down into a fine powder the longer it stays in your chalk bag or bucket, and Petzl Power Crunch Box is also quite chunky.
We evaluated two varieties of liquid chalk, or chalk cream — Friction Labs Secret Stuff and Mammut Liquid Chalk. After drying, Mammut Liquid Chalk has a slightly grainier texture than Secret Stuff, and our testers noticed almost no difference in friction and overall feel between the liquid chalks. We noticed that Mammut Liquid Chalk stays evenly mixed in its tube better than the Secret Stuff, so you'll need to be diligent about shaking the Secret Stuff before applying, or you'll end up just squirting rubbing alcohol on your hands.
Coverage
How much climbing chalk will be stuck on your hands after a dip into your chalk bag? How long will it stay on your hands before you need to chalk up? Another minefield of subjectivity, we tackled this metric with hi-res photos of our hands before and after multiple reps using different holds on our hangboard. Both the liquid chalks shined bright in this metric since, in liquid form, we can rub chalk into every nook and cranny of our hands before it dries. Provided we remember to shake the bottles so the solutions are evenly mixed, both liquid offerings from Friction Labs and Mammut provide equal coverage.
Among the loose chalk, coverage is dependent on how crushed up the chalk is. Fresh out of the bag, the silky feeling Bison Designs Competition Chalk provides the most coverage, caking up in a thick layer on our hands, while Friction Labs Unicorn Dust left a thinner layer both before and after the hanging exercises. Frank Endo Chalk Blocks and Petzl Power Crunch provide much better coverage if we break down the blocks by hitting our chalk bag against the ground and stomping on it. We found we could get similar coverage from all of the loose chalk if we ground it down to its finest form.
Does the rock still feel slippery even though your hands are covered in a fresh layer of chalk? Brush those holds. Chalk tends to stick to more chalk, and eventually, so much chalk will build up on the climbing holds that even the most positive crimp starts to feel slick. Do yourself and your climbing buddies a favor and carry a climbing specific boar's hair brush in your kit so you can brush the chalk off key holds between bouldering attempts or while you're being lowered off a sport climb.
Mess
It seems like any thoughtful, patient adult should be able to get any of these products out of the packaging and into their chalk bags or onto their hands without making a mess. In reality, our testers had chalk all over the floor of the climbing gym, the trunks of their cars, their bodies, and even their faces during our months of testing. If you climb primarily indoors, your gym may require you to use a chalk ball to cut down on the mess. Dust is also starting to become a major concern in crowded climbing gyms. For scoring the mess metric, we considered aspects of how each chalk is packaged, if that packaging is reusable and sealable, and by paying special attention to how much chalk we spilled while loading up our chalk bags.
As long as you don't give them to your five-year-old, the liquid chalks offer a relatively mess-free delivery system. When properly mixed, Mammut Liquid Chalk and Friction Labs Secret Stuff stick to your hands even after they're dry and create very little dust. If you forget to shake up the tubes, you may end up with a dose that's light on the alcohol and will dry very quickly, then flake off your hands and into the air. A few folks use liquid chalk exclusively, but our testers feel that waiting for liquid chalk to dry after every application is impractical because they want to chalk up on the fly, so they always carry loose chalk or a chalk ball.
We've tested chalk balls in the past, and find them to be the most reasonable way to reduce spillage and dust. The cloth sack of chalk only allows a small amount of chalk to pass through at a time, creating less dust than loose chalk in a chalk bag. If you're genuinely concerned about reducing dust in your gym, or you have a very young climber in your life, a chalk ball is your best bet to keep chalk out of the air and off of your belongings. We find that it can be hard to really chalk up well with these products, but they do have their applications.
Loose chalk makes a mess despite our best efforts, but Friction Labs Gorilla Grip and Unicorn Dust are the easiest of the loose chalks to get from their coffee bag style packaging and into our chalk bags. We attribute this to the narrow, resealable openings that are the perfect size for pouring into a chalk bag, while the Metolius and Black Diamond loose chalks have larger openings that permit chalk to spill all over the place. We like to leave a scooper from an old drink mix in the bag with these chalks so we won't have to use our hands to fill a chalk bag. The resealable containers that hold Trango Gunpowder and Petzl Power Crunch also do an excellent job of reining in the mess, especially when they're rolling around inside a backpack. Frank Endo Block Chalk is the most difficult variety to wrangle since random chunks can break off the blocks while you're tearing off the packaging, and it eventually breaks down into very fine dust. Make sure you have some kind of airtight storage sack or Tupperware to store unused block chalk and catch the chalk you spill while breaking up the blocks into chunks small enough for your chalk bag.
What's the Best Value?
We usually keep price out of the picture when trying to compare products at GearLab objectively, but in the case of chalk, we find that the prices vary wildly, while performance does not. For example, Friction Labs Gorilla Grip costs more than twice as much per ounce than Black Diamond White Gold. Is Friction Labs Chalk better than Black Diamond? A few testers thought so, but they were still wary of the price, saying they'd take the Friction Labs over BD if they got free chalk but would happily settle for BD if they were paying for it. Friction Labs claims that their chalk is the purest chalk and has no additives. We have no way of ascertaining this. What we did observe is that Friction Labs provides consistently textured chalk in each bag. The bags of Gorilla Grip we tested had a nearly uniform consistency of marble-sized chunks, while BD and Metolius loose chalks have an assortment of chunks and powder. If you are very particular, you too can pay for chalk that feels the same every time, but we suspect performance has more to do with the individual than the brand of chalk.
The best value far and away goes to Metolius Super Chalk, which you can purchase in a 425-gram bag at well under a dollar per ounce. While some of our testers say Super Chalk is their least favorite because of its “silky” texture, it still performed well in our blind tests. The Bison Designs Competition is even less expensive, but our testers universally agreed that this chalk is too fine, and it was actually the easiest to identify during our blind test. BD White Gold is also a decent value at just over a dollar per ounce. Frank Endo Chalk Blocks, despite often being sold by the pound, are over a buck per ounce. Gorilla Grip goes for two and a half bucks per ounce unless you choose to subscribe, which scores you a 10% discount.
Friction Labs Secret Stuff suffered in the value metric with a price over seven dollars per ounce, making the Mammut Liquid Chalk seem like a bargain, costing under two bucks per ounce. We found the difference in performance between these products to be marginal, and we wholeheartedly recommend going with the less expensive option, or even making your own.
Conclusion
Comparing chalk is difficult, and some of our testing monkeys gave us strong, contradicting opinions. Even worse, a few testers had trouble discerning any differences between the loose chalks during our blind testing exercises. We've highlighted the key differentiating factors between these creams, shots, balls, and a variety of loose chalks, so now you'll know what to use and when, and now you can decide if chalk matters to you.
