Mammut Taiss ML Men's Fleece Jacket - Tschiel

Designed for year-round mountain use, the Taiss ML stands out thanks to its Polartec Power Stretch construction. This four-way stretch fabric combines thermal support, effective moisture wicking, and quick drying. The result: you stay warm during static phases and perfectly regulated during exertion.

With its remarkable warmth-to-weight ratio (5/6), this midlayer performs just as well during a sustained climb as it does during a more challenging descent. Its Athletic Fit hugs the body without compressing it, promoting effective insulation under a hardshell jacket.

Mammut Taiss ML Men's Fleece Jacket: freedom of movement and comfort under gear

In climbing and mountaineering, every detail counts. The Taiss ML features a functional gusset under the arms for optimal freedom of movement during technical passages. Flat seams reduce friction, especially under backpack straps.

Thumb loops keep the sleeves in place when layering. The two zippered pockets, positioned higher up, remain accessible even with a tightly fitted harness or waist belt.

A versatile ally for all your alpine adventures

This fleece jacket is suitable for a wide range of outdoor activities. It excels in the following disciplines in particular:

• Climbing and via ferrata
