evo.com | Crab Grab Ski and Snowboard Mittens > What do you get when you combine the design of ultra-warm gloves with ultra-durable ones? The Crab Grab Champ Mittens excel in every condition. Padded with fleece and Primaloft insulation, the Champ has super durable nylon for the ultimate combination of hardcore and soft warmth. PrimaLoft(R) Grip-Control Palm Insulation This special blend of PrimaLoft(R) was originally developed for winter footwear applications. The fibers are structured to minimize lateral sliding, providing an anti-slip, super stable surface, which works wonders for increasing your grip power. Heavy-Duty Woven Nylon Shell Crunch Grip(TM) Thumbs Incredibly grippy silicone-injected microfiber panels for added grip. PrimaLoft(R) Insulation Originally developed for the military as a water resistant, synthetic alternative to goose down in sleeping bags, PrimaLoft(R) provides goose down level heat, while still excelling in wet environments. 15K Dry Claw(TM) HIPORA(TM) Membrane Crab Grab customized 15K Hipora(R) membranes are waterproof, breathable 3-layer membranes that encapsulate our insulation and liners. The membrane's microporous structure allows water (melting snow and rain) from entering, while allowing water vapor (your sweat) to escape. | Crab Grab Champ Mittens 2025 - X-Large in Brown | Nylon
