Mammut Aconcagua Light Midlayer Jacket Men 69193383

The Mammut Aconcagua Light Midlayer Jacket Men is a slim-fit fleece top designed as a midlayer for outdoor adventures in cool conditions. With a full-length zipper and stretch fabric, it works well over a base layer or under a shell. It provides lightweight warmth without restricting movement during hiking, climbing or daily wear.

Crafted from 89% polyester and 11% spandex with Polartec® Power Grid™ technology, this jacket balances insulation and breathability. The stretch fleece ensures freedom of movement, while the grid construction traps warm air close to your body and lets moisture escape. Additionally, its slim fit reduces bulk under a shell and keeps the fleece close to your layers for consistent warmth.

Polartec Power Grid™ features a raised grid pattern on the fabric’s interior that creates pockets of air, boosting thermal efficiency without adding weight. The polyester content delivers durability and quick-drying performance, and the spandex adds stretch for comfort during activity. Bluesign® approval, Fair Wear certification and use of recycled materials reflect Mammut’s commitment to responsible production.
