What Not to Wear: Climbing in Hot Weather

Doing anything outside when it’s really hot can be uncomfortable, and climbing in hot weather is no exception. You may not get quite as sweaty as you do during other activities, but you’ll still get pretty ripe, and wearing the wrong clothes will only make matters worse.

In an effort to save you from some really uncomfortable experiences when when climbing in hot weather, here are a few What Not To Wear items along with some rock climbing apparel suggestions for more comfortable days at the crag.

WNTW #1: Cotton tees/tank tops

If you’ve been doing outdoorsy things for a while, you’ve no doubt heard the phrase “Cotton Kills” and just because climbing isn’t necessarily as high-intensity as hiking or trail running doesn’t mean you won’t work up a healthy sweat. The ensuing sweat stains on a cotton tee are not only super gross for your climbing partner(s) to have to look at all day, they also take forever to dry and will make you really uncomfortable. Unless it’s so hot out that you decide to climb in an air conditioned gym, leave the cotton tees at home.

Eastern Mountain Sports Brand Ambassador and pro climber Joe Kinder LOVES climbing in cotton shirts in the spring and fall, but for everyone else, synthetic is a better choice.
Alternative: Synthetic tees/ tank tops

It’s pretty common knowledge that synthetic shirts are a much better choice for lots of hot-weather activities. Climbing is no different. Synthetic tees, like Techwick, pull moisture away from your skin and somehow magically reduce the size of your sweat stains. They also dry waaayyyy faster than their cotton counterparts, so you’ll be a lot more comfortable.

WNTW #2: Black, or other dark colors

On a related note, also leave anything black at home. Assuming you were raised by humans instead of wild animals (you can’t listen to wild animals)they know nothing about dealing with hot weather except that the’re physiologically superior at it), you already know that dark colors absorb heat, which in turn makes you feel even hotter. So save your goth/emo/ninja look for another (less hot) day.

Alternative: Light colors

The rules of logic indicate that if dark colors absorb sunlight/heat and make you feel hotter, then lighter colors will reflect sunlight/heat and help you not feel quite so hot. Keep this in mind when getting dressed for a hot day of climbing and you’ll be a lot happier.

WNTW #3: Short shorts/Basketball shorts

Ladies: Short shorts are one of those things that seem like a good idea at the time. You think, it’s really hot out, so I want to wear as little as possible. But then you start climbing and realize that not only are you probably giving your belayer an awkward free show every time you need to high step or heel hook, but your harness is super uncomfortable when it’s digging directly into your skin. There are plenty of other opportunities to rock your booty shorts during the summer: don’t torture yourself by wearing them at the crag.

Guys: You’re not playing basketball when you’re climbing, so don’t dress like you are. The bagginess of basketball shorts will most likely lead to really uncomfortable bunching once you put on your harness and you’ll spend more time trying to fix the issue than you spend actually climbing. Just don’t do it.

This guy seems to be doing well in his basketball shorts but looks can be deceiving. I’m not a guy, but this can’t be comfortable.
Alternative: Normal shorts

Shorts and capris specifically designed for climbing are abundant. They’re made from lightweight materials, offer the perfect amount of stretch, and have a gusseted crotch (which both makes the shorts more comfortable and helps prevent any embarrassing mid-climb tears).

For the ladies, something like the Prana Audrey Knickers are perfect. Sure, they may be a little long, but trust me: Prana has been in this game for a long time, and they know a thing or two about how to keep you comfortable. If you want something shorter, though, anything that meets the aforementioned criteria (lightweight, stretchy, gusseted crotch if possible) will do the trick. And, for the guys, there’s a good reason the Prana Mojo shorts have been a favorite for pretty much forever. Once you climb in a pair of these bad boys, you’ll want a pair or two in every color.

WNTW #4: Birthday suits

Sure, Chris Sharma and his ladyfriend, Daila Ojeda, recently spent a day bouldering at the Buttermilks naked, but it was for an ESPN photo shoot. I’m 96.4% certain they don’t do that on a regular basis. Please, for the sake of everyone else around you, do not climb in your birthday suit. If it’s so hot out that you’re tempted to even consider it, you should probably wait for a nicer day (or simply take your climbing indoors).

OK, maybe Chris Sharma and Dalia Ojeda CAN get away with climbing naked, but most of us don’t have the skills or the physiques.
Alternative: Go shirtless if you must

If it’s really, truly, unbearably hot out, then taking off your shirt is a good way to help keep cool. (Just remember to cover up with sunscreen!)
