Women's Taiss Pro Belay IN Hooded Jacket 25/26

Built for bitter cold, long belays, and the kind of winter missions where stopping means losing heat fast, the Taiss Pro Belay IN is Mammut’s answer to serious alpine insulation. Designed to fit over your hardshell without restricting movement, this belay parka delivers an incredibly technical balance of warmth, durability, and weather protection. DRY DOWN insulation brings high loft and reliable performance even in damp conditions, while strategic synthetic fill reinforces high-wear zones and keeps insulation consistent where it matters most.

The 10D Pertex® Quantum Pro shell adds impressive abrasion resistance for its weight, shrugging off ice, pack straps, and rough granite with ease. Boxwall construction eliminates cold spots, allowing the down to fully loft and trap heat efficiently, and an internal neck gaiter locks in warmth during exposed belays or frigid transitions. With oversized VISLON® zippers, glove-friendly pulls, and high-set pocket placement, the whole design stays functional even when you’re layered up and moving in full winter kit.

From bivy ledges to mixed-climbing objectives, this is the belay jacket built to keep you warm enough to stay sharp and keep climbing.
