Mammut

Crag IN Jacket - Women's

What Our Gearhead® Experts Are Saying:

"This jacket surprised me with how warm it stays for the weight. LOOPINSULATION handles damp conditions better than down, and the fit is clean enough to wear around town but technical enough for hikes. It’s a great grab-and-go winter layer."

Cold trails, breezy ridgelines, and everyday winter errands all feel more comfortable in the Crag IN Jacket. Mammut builds this layer with LOOPINSULATION, a recycled synthetic fill derived from repurposed rope scraps that creates dependable warmth even when the weather turns damp. Paired with a recycled outer fabric and a PFC-free DWR treatment, it offers wind and moisture resistance while keeping the weight minimal.

Throughout the day, elastic cuffs and a smooth hem keep warmth close without restricting movement, and zippered pockets secure essentials or warm chilled hands. The regular fit layers effortlessly over fleece or base layers, making the jacket versatile enough for both outdoor mileage and laid-back winter outings.
