Taiss Pro Belay IN Hooded Jacket – Women’s

What Our Gearhead® Experts Are Saying:

“I rely on the Taiss Pro Belay IN when standing still in brutal cold. The DRY DOWN insulation keeps loft even in damp conditions, and the boxwall construction really eliminates cold spots. I appreciate the oversized zips and pulls—they’re easy to manage with gloves—and the fit layers cleanly over a shell without feeling restrictive.”

We trust the Taiss Pro Belay IN Hooded Jacket from Mammut for the coldest moments in the mountains—long belays, exposed bivies, and wind-scoured transitions where warmth is non-negotiable. It’s built to go on fast over a hardshell and lock in heat when movement stops and conditions turn unforgiving.

The Pertex Quantum Pro outer fabric provides durable weather resistance, while DRY DOWN insulation delivers reliable warmth even when moisture creeps in. Boxwall construction maximizes loft and minimizes cold spots, and strategically placed synthetic insulation reinforces high-wear, high-exposure zones like the shoulders, forearms, and collar. A helmet-compatible hood, internal neck gaiter, and high-mounted hem adjustment seal in heat, making this jacket a dependable refuge in sub-zero alpine environments.
