Critical core heat in a super-compressible, sleeveless version of our bestselling insulator. When the team riders wanted the heat, but without those pesky sleeves, our design team got out the scissors. The result is the vest version of this ultra-lightweight, highly-packable backcountry-proven piece. The Burton [ak] BK Down Insulator Vest shares the same water-repellent ripstop fabric and ultra-premium 800-fill RSD down of its ever-popular counterpart. Fleece-lined handwarmer pockets defrost frozen fingers and a zippered chest pocket stows key items. With maximum compressibility, it packs down small enough to throw into even the smallest riding pack or travel bag.
