Mammut Waymarker Insulated Jacket Women's

The Waymarker Insulated Jacket Women’s by Mammut is a lightweight down jacket built to add a reliable layer of warmth when temperatures dip on trail or at camp. It’s designed for everyday outdoor use, offering a balance of insulation and packability without unnecessary bulk.

Constructed with a Pertex® Quantum shell and filled with duck down, this jacket delivers a strong warmth-to-weight ratio while remaining breathable. At just 342 grams, it tucks easily into a backpack and moves with you thanks to its Regular Fit cut. The 100% polyester outer is PFC-free, so it sheds light moisture without relying on harmful chemicals, and the recycled down insulation helps reduce environmental impact without compromising performance.

Pertex® Quantum is a tightly woven, ultralight fabric that resists wind and abrasion, helping the down loft fully and lock in heat. Bluesign® certification indicates that every step—from material sourcing to production—meets strict environmental and safety standards, and Fair Wear certification shows the people who made the jacket were treated ethically.
