Inspired by our athletes with a thirst for lighter, faster-climbing gear, the Advanced Mountain Kit is the most sophisticated alpine climbing system we've ever created. Combining a long gauntlet, lightweight FUTURELIGHT™ shell and leather palms the L3 Insulated Gloves provide a balance of warmth, protection and dexterity. They feature PrimaLoft® Gold insulation throughout for advanced warmth in a broad array of conditions.
