A tough GORE-TEX shell for big lines in the backcountry or resort. From lift lines to backcountry spines, the Sentinel Jacket remains a durable classic for deep-snow ambitions in rugged terrain. Built with the features you need to keep comfy while stepping out of your comfort zone like 3L GORE-TEX ePE that uses a tough 100d face fabric , and a modern, women’s-specific fit provides better articulation. A helmet-compatible StormHood™ , snow skirt, and hem adjuster keep weather on the outside, while a thin layer of soft-backed flannel keeps you cozy on the inside.
