More importantly, it allows your body to breathe, so you’re not left a sweaty mess after you have to step on the gas to get through the crux.

PROVENANCE AND ETHICS
Originally founded as Rock Solid Manufacturing by David Lane in 1981, In 1990 Lane brought Jeremy Guard, a fellow climber, into the fold and in 1991 they renamed the company Arc’teryx - a nod to the Archaeopteryx lithographica, the first reptile to develop feathers for flight - the first bird - and the brand’s instantly recognisable logo is a depiction of the Berlin specimen of the Archaeopteryx. Their philosophy is guided by the belief that durability is the strongest path to sustainability.
