An insulated GORE-TEX jacket for sending it in the coldest depths of winter. There’s nothing like bluebird days for ticking off lines, but clear skies often mean biting cold. The Sentinel Insulated Jacket is made to keep your blood flowing so you never miss a day. It’s built with the same dependable weather protection as our shell jacket but packed with intentionally mapped insulation that’s lighter under the arms . A more contemporary, women’s-specific fit allows for maximum freedom of movement in the burliest terrain, while a 2L GORE-TEX e PE membrane and 100d face fabric provide breathable toughness.
