Heat up your layering system with the Burton AK BK Insulator Jacket.
Layer the Burton Men's AK BK Insulator under your shell for no-frills, lightweight warmth. This insulating jacket's 700-fill goose down insulation keeps your upper-body cozy warm without limiting your mobility, whether you’re shredding in the park or dropping in on a massive heli line. The full-length Underarm zips match those on your shell jacket for quick, efficient ventilation during strenuous hikes. In cold, clear weather or on the street, wear this Burton insulating layer by itself. A chest pocket and fleece-lined handwarmer pockets give you a place to stash your iPod and warm up cold hands. **DISCONTINUED**
