The Burton AK Helium jacket combines light weight, shell-friendly features and synthetic Primaloft insulation.
For serious backcountry travel, lightweight gear and insulation are essentialâ€”especially insulation that won't be made useless if it gets wet. Designed to work in perfect harmony with any of the Burton AK shells, the AK Helium Insulated Jacket with body-mapped Primaloft synthetic insulation keeps you toasty in the nastiest winter months without ever interfering with your shell's functionality. In fact, the Helium's insulated pockets are designed to be easily accessed through your shell's underarm vents, and the Helium's stowaway hood gets completely out of the way when you would prefer to use the hood on your shell. Best of all, Primaloft insulation still retains most of its heat-saving properties when disaster strikes and your jacket is soaked through.
