Mammut Aconcagua Light ML miesten fleece-takki musta

The Mammut Aconcagua Light ML redefines what a fleece jacket can be, merging the insulating power of a mid-layer with the unrestricted movement of a technical base layer. Crafted from Pontetorto Tecnostretch fabric—a 92% polyester, 8% spandex blend—it delivers exceptional four-way stretch for steep climbs while efficiently trapping heat. This jacket is built for athletes who demand performance without bulk.

Highlights

• Pontetorto Tecnostretch: 92% polyester, 8% spandex for high elasticity and durability
• Athletic fit layers easily under hardshells without restricting motion
• Full-length front zipper with high collar seals out drafts
• Two zippered side pockets secure small essentials

• bluesign® PRODUCT for responsible manufacturing

In daily use

Built for motion, the Aconcagua Light ML moves with you. The stretchy fabric and articulated cut make it ideal for climbing, mountaineering, and hiking. Use it as an insulating layer under a shell on cold days, or as a standalone for high-output activities in mild conditions. The smooth face resists snags, while flatlock seams prevent irritation under pack straps.
