Mammut's Casanna Glove doesn't just stop at being warm and waterproof, it's also made with all things sustainable. In addition to using recycled polyester and eco-friendly dyes, the leather at the palm is chrome-free and wears out far more slowly than synthetic materials. But don't worry, two-layer wind- and waterproof technology defends your hands against wet weather and winter winds, and synthetic insulation delivers reliable warmth that's body-mapped for mobility. Gauntlet cuffs extend over your sleeves for extra coverage, and the pre-shaped hand feels natural while you play on the slopes.
