Whether we're hitting deep powder laps or tackling backcountry tours, the Black Diamond Spark Mitten keeps our hands warm and dry through it all. The tough goat leather exterior and BD. dry waterproof insert protect against the elements, while PrimaLoft Gold insulation ensures our hands stay toasty during long days in the cold. Inside, the mitt's finger slots boost dexterity without sacrificing warmth, and the neoprene cuff fits snugly under our jacket to keep snow out. Plus, the added EVA padding gives extra protection when we're brushing past branches or taking on more rugged terrain.
