Arc'teryx Women's Sentinel Jacket

The Arc’teryx Women’s Sentinel Jacket is a technical waterproof shell designed for snowsports and winter alpine use, where sustained precipitation, wind, and cold demand reliable protection and breathable performance. Engineered to handle everything from resort freeride days to backcountry skin tracks and storm cycles, this jacket balances robust weatherproofing with articulated mobility and functional features for dynamic mountain activity. At its core is a PFAS-free GORE-TEX ePE waterproof, windproof, and breathable membrane that defends against heavy snow, sleet, and wind while allowing body moisture vapor to escape. The durable face fabric stands up to abrasive contact with packs, ropes, and ski edges, making it suitable for repeated use in harsh winter conditions. This waterproofing system serves as a strong foundation for cold-weather layering systems where external moisture exclusion is a priority. The Sentinel Jacket’s cut incorporates Arc’teryx’s articulated patterning and regular fit, providing freedom of movement during high-reach motions like skinning uphill or controlling descents on variable terrain. A helmet-compatible StormHood™ offers coverage that integrates with alpine helmets without blocking peripheral vision, adding protection against wind and snow. Adjustable cuffs and a helmet/harness-friendly hem cinch allow fine-tuned personalization of fit and coverage. Ventilation is managed through well-placed pit zippers that release excess heat during uphill skinning or brisk movement, helping regulate internal moisture without compromising protection from the elements. Secure hand pockets and a high-ride storm flap over the center zipper protect stored essentials while keeping snow and wind at bay. Designed to layer over insulating pieces, the Sentinel Jacket functions as a cornerstone of a winter outerwear system for snowsports and alpine travel. Overall, the Women’s Sentinel Jacket is built for outdoor adventurers who want rugged waterproofing, breathable performance, and purposeful design details that support long days in cold, snowy, and windy mountain environments.
