Item #: 331819243

Created for backcountry skiing and snowboarding, but flexible enough for a range of winter mountain sports, the Fission Mitten is built warm, dry and tough. It combines the proven waterproof breathable protection of GORE-TEX® XCR product technology with the efficient thermal performance of three types of Primaloft® insulation. The hardwearing Fortius™ 1.0 softshell outer delivers stretch with abrasion resistance. Rugged, supple leather reinforces the palm and fingers and helps provide a secure grip.
