Norrona's most durable waterproof mountaineering pants.

These lightweight shell pants are made for demanding alpine climbing but work perfectly for all-season mountaineering adventures, both with or without skis and crampons.

The pants are made in premium GORE-TEX® PRO fabric, and we use this because it’s the world-leading quality for durable waterproofness (28,000mm), optimized breathability, and total windproofness.

The main fabric is a 3L 70D GORE-TEX® PRO most breathable fabric (RET 6) with a 100% recycled nylon face. This ensures durable, reliable weather protection and optimized breathability at a lower weight, perfect for active movement.

On the upper part, which is less exposed, we use a 3L 40D GORE-TEX® PRO most breathable (RET 6) 3-layer, 40D recycled nylon that is thinner and gives less bulk.

Key features include a functional ? side two-way zipper for good venting options, a Custom-fit waist system, two zippered thigh pockets, adjustable ankle width, a bootlace hook, Vectran reinforcement on the lower leg, and eyelets if you want to fasten a cord around the boot to make sure it stays in place. The pants are suspender and bib compatible.

The pants have a technical fit with articulated knees and an ergonomic S-shape to improve mobility during vertical movement and decrease excess. In addition, the bottom legs can be expanded to fit ski touring boots.
