It's really hard to maintain the perfect hand temperature when shredding. One day it's -50°, the next you're sporting a T-shirt. The kids' Burton Vent Mitten aggressively tackles roller-coaster weather with a simple ventilating pocket that also accommodates a disposable handwarmer. When it's warm, open the vent. When it's cold, stuff a heater inside. Kid-tough DRYRIDE 2L fabric combines with our waterproof DRYRIDE Membrane 2.0, along with a midweight level of Thermacore insulation for warmth and weatherproofing that endures all season.
