Arc'teryx Women's Sentinel Bib Pants

The Arc’teryx Sentinel Bib Pant Women’s is a 3-layer waterproof shell bib engineered for ski touring, backcountry expeditions, and high-alpine freeride days. Built to withstand sustained snowfall, wind, and the rigors of mixed mountain terrain, this bib pant integrates technical weather protection with mobility and functional features for extended winter use. At its core is a durable GORE-TEX ePE waterproof, windproof, and breathable membrane that shields the wearer from deep powder, wind-driven snow, and wet weather encountered on steep lines or long tours. The 80D face fabric provides abrasion resistance and durability, while a soft brushed backer improves on-body comfort — important when moving through varied activity levels in cold conditions. The bib design extends coverage above the hips, reducing snow intrusion during deep powder sessions and keeping insulation systems and base layers dry. Adjustable suspenders and a drop seat panel add convenience during long days in the field. Ventilation is managed through large thigh vents that release heat efficiently on uptracks or during high-output efforts, helping regulate temperature without sacrificing protection. Functional storage includes multiple secure pockets, and embedded RECCO® reflectors offer an added layer of search-and-rescue visibility. Articulated patterning allows for a natural range of motion during skiing, hiking, or skinning, and reinforced cuffs and gaiters help seal out snow at the boot interface. Overall, the Sentinel Bib Pant Women’s is designed for serious snowsports users who demand waterproof performance, durability, and thoughtful features in variable alpine conditions — from resort freeride laps to long backcountry missions.
