The hybrid design combines mitten-level insulation with glove-like dexterity, so you get serious warmth without sacrificing the freedom to move. Cozy HeatLock™ fleece keeps hands warm without overheating, while strategically placed WindStop™ panels block icy gusts across your knuckles and fingertips. When the weather gets truly brutal, the zipper pocket fits a hand warmer for extra heat when you need it most.
