"What Our Gearhead® Experts Are Saying:""I packed this for a few cold alpine days, and it’s impressive how warm it is for the weight. It compresses down small, and when I pull it out during breaks, the heat is immediate and really even.""When we’re moving through cold alpine terrain, every ounce matters, and the Odin LT Down Jacket from Helly Hansen delivers the warmth we need without slowing us down. Designed for mountaineering and high-output days, it packs down small in our kit and comes out ready when we stop moving, whether we’re layering up on a ridge or taking a break below the summit. The streamlined build keeps things efficient while still holding onto critical warmth. A unique down sheet construction distributes insulation evenly, eliminating cold spots and improving overall heat retention. The insulated hood, along with elastic cuffs and hem, helps seal in warmth while keeping weight low. A RECCO® reflector adds an extra layer of safety in remote terrain, and the jacket packs into its own stuff sack for easy storage. Built with recycled materials and a PFC-free DWR finish, it’s designed for repeated use in demanding conditions."
