From ski break to gear down this slick and warm puffy folds new style into predictable backcountry settings. 100-gram Primaloft® One and recycled Mirage™ fabric create the right mix of warmth and dryness, while underarm panels stretch and breathe. The compressible, synthetic fill stays toasty even in wet storms and slides easily under a shell on cold days, over a soft shell on backcountry descents.
