A low-profile design that integrates under any Burton AK shell, the Burton AK Helium Insulated Jacket provides warmth in cold conditions without the extra bulkiness. PrimaLoft® insulation keeps you toasty even when wet and is engineered with extra loft in the sweet spots for maximum efficiency. This lightweight insulated jacket is built with buttery soft, water-repellent fabric to reduce layering friction and shed moisture when exposed to the elements. Integrated handwarmer pockets allow easy access through pit zips of AK shells. The AK Helium offers maximum warmth without restricting mobility and comfort.
Buttery Soft Heathered DWR Coated Fabric The Durable Water-Repellent coating is formulated to break down the surface tension of any moisture that comes into contact with it—causing water droplets to bead up and roll off before they crash your party.
PrimaLoft® Insulation Originally developed for the military, PrimaLoft’s extremely lightweight core structure suspends millions of air particles in a microfiber mesh. These microscopic air particles repel water while trapping heat to keep you warm in the nastiest conditions, even after repeated washings.
[ak]™ Fit Focused on providing an even more performance oriented, articulated fit for high-energy riding. With cutlines and patterning engineered to mimic the body’s natural flex while riding and hiking, the result is a higher degree of mobility that enhances the function-first design and style of [ak].
