The Women's Arc'teryx Sentinel Insulated Pant is a ski and snowboard pant for backcountry adventure and days at the resort. It all begins wit GORE-TEX for waterproof, breathable protection, and is packed with Coreloft insulation for plenty of warmth when the temps drop low. Zippered pockets secure your phone and lip balm so you won't litter the mountain, and a hidden RECCO reflector will aid search and rescue teams in the event of an avalanche. Open up the thigh vents when you're working hard and looking to dump excess heat, and trust the Keprotec instep patches for extra durability against sharp gear, from boots to ski edges.
