Mammut Taiss ML Hooded Jacket Men's Black S - 4-Way Stretch Technical Mid-Layer

When the mountain throws shifting winds, sudden squalls, and steep terrain at you, a static mid-layer simply isn't enough. The Mammut Taiss ML Hooded Jacket is built for movement—engineered with a 4-way stretch Pontetorto® Tecnostretch fabric that moves with you, not against you, during high-output pursuits like ski touring, climbing, and alpine hiking. Its athletic fit and close-fitting hood layer neatly under a shell, while flat seams reduce chafing when you're swinging an ice tool or reaching for a hold.

Who is it for

This is for the mountaineer, ski tourer, or trail hiker who demands a breathable, quick-drying mid-layer that can handle sustained effort without overheating. It's equally at home on a cold-weather trek or as a versatile piece for everyday mountain wear. The men's version in black, size S, offers a streamlined silhouette that won't bulk up your layering system.
