Because your ambitions don’t dip when the temperature does, the Sentinel Insulated Pant is designed to keep your blood flowing any time you drop in. Built with the same tough all-weather protection as the shell pant but packed with thermomapped insulation, the 2L GORE-TEX ePE membrane and 100d face fabric provide breathable toughness, while a more contemporary women’s fit allows maximum freedom of movement. What's been updated: The Sentinel Insulated Pant’s face fabric has been upped from 80d to 100d for more toughness and durability. We’ve also updated the fit throughout the leg for more room and added a new instep patch made with Hadron® yarns to improve durability and weight, while also being flexible to prevent bunching. There’s more room in the thigh pockets and easier access as well, thanks to a pleated opening and new bellowed design.
