As the toastiest insulated Gore-Tex jacket in Burton's line, you can count on the Burton Men's AK 2L Helitack Insulated Jacket to help you stay blissfully warm as you surf bottomless powder in bone-chilling temps. Storm day refills and drizzly coastal conditions will stay out on the mountains where they belong with the Helitack's bluesign-approved Gore-Tex two-layer membrane guarding against water and wind, while enterprising PrimaLoft insulation traps your own body heat within its thermally efficient synthetic fibers to keep you warm. These synthetic fibers are not only extremely light and packable, but they're also resistant to moisture and condensation build-up for high levels of warmth in wet conditions. Evenly distributing heat, the quilted downproof lining prevents the PrimaLoft insulation from migrating throughout the jacket so you continue to enjoy allover warmth for years to come. Fully sealed seams and YKK water-resistant zippers refuse to give stubborn drops of water the opportunity to soak you, while features like a removable powder skirt, jacket-to-pant compatibility, and mesh-bound internal pockets all work to make life easier when all you want to do is get out in the pow.
