The Marmot Sidehill Glove will take your love of aggressive arctic action to the next level. Washable hair sheep and pigskin leathers offer resilience and pliability, and the MemBrain Insert is both waterproof and breathable. Molded d3o protective padding remains soft and flexible until the moment of an impact, when it instantly stiffens -on a molecular level- to protect exposed knuckles, fingers, and palms.
