Lightweight and highly protective Alpine climbing pants built with GORE-TEX Pro; fully waterproof performance for the most technical lines. Originally developed as a bespoke product for our own team of Alpinists the Tupilak Atmo Pant was a response to their need for lightweight but fully protective shell trousers for their biggest and steepest projects around the world. With our tailored Alpine fit these are the only choice for the most exposed situations.
