The Flylow Mighty Mitten is a waterproof leather mitten built to keep a kid's hands dry through snow forts and ski lessons alike. A PFAS-free DWR treatment coats the pigskin leather shell, backed by a 10K/10K waterproof lining that blocks moisture without relying on forever chemicals. Zoned insulation adds extra warmth across the back of the hand while keeping the palm thinner for a better grip on a sled rope or a ski pole. What Our Gearhead(R) Experts Are Saying:"My kid came in from two hours of snow forts with completely dry hands, no soggy liner to peel off at the door. I didn't have to think twice about what treatment was on the leather."
