Mammut Taiss ML Men's Fleece Jacket Blue

A technical mid-layer fleece jacket built for high-output alpine pursuits, the Mammut Taiss ML delivers exceptional warmth-to-weight performance with Polartec Power Grid fabric. Its four-way stretch and athletic cut ensure unrestricted movement and seamless layering under a shell, while the moisture-wicking, quick-drying material keeps you dry during intense ascents.

Advantages

Polartec Power Grid efficiently regulates body temperature, providing warmth without excess bulk. Weighing only 280 g (size M), this jacket packs easily and layers comfortably. The 4-way stretch fabric and flatlock seams deliver unrestricted mobility and chafe-free wear, while the moisture-wicking, quick-drying fabric keeps you dry during intense activities. A high collar and full-length front zipper offer weather protection and easy venting, and a zippered chest pocket secures small essentials. Thumb loops keep sleeves in place and add hand warmth.
