Whether you're belaying or setting a route, harnesses can do some funky things to your pants, especially your crotch. To avoid the feeling you're climbing in a man thong, pull on a pair of The North Face's Men's Granite Dome Cargo Pants. With their harness-friendly design, you won't get any uncomfortable bunching in your britches while you're on belay. While you're climbing, articulated knees, gusseted crotch, and a cotton nylon stretch material will help you get that last hold, and with their UPF rating of 50, you'll get some added protection from the sun.
These innovative climbing cargo pants have a harness-friendly design and combine the comfort of cotton with the performance and durability of nylon for long-lasting wear.
