The Black Diamond Iris Glove uses a combination of Prim aloft Gold Insulation and a zippered heater-pack pocket to keep your hands warm through the most frigid ski days. Total weather protection comes from the GORE-TEX XCR waterproof breathable membrane, so you can ski though the storm with confidence. The Iris Glove also features an ultra-durable goat leather palm for increased durability, so you can use it season after season.
