Mammut Women's Aconcagua ML Hooded Fleece Jacket Dark Mammut Red

The Mammut Aconcagua ML Hooded Jacket sets itself apart from ordinary fleece mid-layers by combining Polartec Power Grid fabric with an athletic, climbing-specific cut. This women's jacket delivers targeted warmth where you need it while remaining exceptionally breathable and lightweight—ideal for high-output alpine activities. The four-way stretch knit moves with you through every reach and stem, and the close-fitting hood adds core warmth without restricting peripheral vision or helmet compatibility.

Highlights

• Polartec Power Grid fabric: 89% polyester, 11% spandex for efficient thermal regulation and flexibility
• 4-way stretch material ensures unrestricted movement during dynamic climbs and ski tours
• Close-fitting hood adds warmth without bulk, fits comfortably under a helmet
• Full-length YKK Vislon front zipper for easy ventilation and layering
• Two zippered side pockets secure small essentials like keys, lip balm, or a topo map
• Elastic cuffs with integrated thumb loops keep sleeves in place and seal out drafts
• Flatlock seams reduce chafing and improve durability for long days in the mountains

In daily use

Whether you're breaking trail on a cold morning or reaching for a high hold, the Aconcagua ML Hooded performs. The high collar seals in warmth when zipped up, while the thumb loops integrate smoothly with outer layers. Breathable and moisture-wicking, it moves moisture away from the skin to keep you dry during intense efforts. The fabric also offers UPF 30+ protection for exposed mountain environments. This mid-layer is equally at home as a standalone on cool rock routes or as part of a layering system under a hardshell during winter ascents.
