Marmot built the Exum Guide Gloves to excel in the nasty conditions that hardcore adventurers find while mountaineering, ice climbing, and skiing. Exum guides are some of the best in the world, and the philosophy behind designing these gloves was that those guides deserved the best gloves in the world. Marmot gave the Exum a snow-proof, waterproof, breathable MemBrain as well as durable, stretchy Falcon Grip for extra dexterity with ropes and gear. In addition, the layer of Thermal R insulation locks in your fingers' heat during legendary mid-winter ascents and descents, and the leather reinforcement keeps this glove in good shape despite daily mountain abuse.
