Insulation for Cold Weather Built for alpine environments where dependable warmth is essential, the Helium Down Mitt delivers lightweight insulation for cold-weather mountain pursuits. Wear it on its own to keep hands warm around camp, during transitions, or whenever activity levels drop. When conditions turn wet, snowy, or more severe, pull a waterproof shell mitt directly over the Helium Down Mitt for an added layer of weather protection while maintaining the warmth underneath. A 100% recycled nylon 20D ripstop shell provides lightweight durability and wind resistance, while RDS Certified 700 fill down insulation on the back of the hand delivers exceptional warmth with minimal weight. PrimaLoft® Cross Core™ synthetic insulation in the palm maintains thermal performance while enhancing grip, dexterity, and moisture resistance in high-contact areas. Inside, a 140g Tricot Microbemberg palm lining and low-cling woven polyester back-of-hand lining enhance comfort and moisture management. Combining lightweight warmth, packable insulation, and layering versatility, the Helium Down Mitt is built for alpine pursuits where maintaining warmth before, during, and after movement is critical.
