Developed by the team of dedicated athletes and skiers at Black Diamond, the Progression Mitts combine performance, thermal comfort, and style. The Gore-Tex® insert makes them waterproof and breathable, while the PrimaLoft® Gold Cross Core insulation ensures you stay warm. With a reinforced goat leather construction in high-wear areas, the Progression Mitts offer durability that can handle intensive days. Even on days with heavy snowfall or extreme cold, these Black Diamond ski mitts are up to the task! The EVA padding on the back of the hand and thumb further increases the level of protection. For continuous thermal performance, the neoprene wrist with Velcro closure is reliable and effective. The ideal protection for days when the snow is flowing.
