What Our Gearhead® Experts Are Saying:“This jacket surprised me. It’s warm without being bulky, ventilates well on the skintrack, and doesn’t flinch on storm days. The detachable hood and wrist cuffs are smart adds that make it more versatile than most insulated shells I’ve worn.”We count on the Boulder Gear Downslide Jacket to keep us comfortable and in control when the weather throws its worst at us. Built for high-elevation riding and cold resort days alike, this fully seam-sealed jacket blends protective shell tech with synthetic insulation for warmth that doesn’t quit, no matter how hard the snow is coming down. Its BG ULTRACORE™ shell delivers 10K/10K waterproof breathability, while mapped synthetic fill keeps key zones warmer without overheating. When we’re bootpacking or riding hard, we open the underarm vents for fast heat release. From the removable hood to the internal gaiter and fleece-lined collar, every detail is designed to keep us charging without compromise.
