HEATWAVE PUFFER JACKET GN-S-017
Ultralight. Ultracozy. The Heatwave Puffer Jacket.
Built to keep you warm without weighing you down, this jacket punches way above its weight with an exceptional warmth-to-weight ratio. It’s super lightweight, packs down small, and works just as well in your kit as it does in your everyday wardrobe.
Intentionally simple and streamlined, there’s less that can fail—and no baffles means fewer cold spots, delivering consistent warmth throughout. The insulation is a next-gen synthetic sheet from Toray, engineered with mechanical crimping to hold its loft and shape, even after repeated use and washing.
Details include elastic cuffs with thumb loops to lock in heat, and a removable hem adjuster for dialing in fit—or shaving off grams when needed.
Whether you’re layering up for camp or boosting your sleep system, the Heatwave is a go-to piece of static insulation that’s light, warm, and always ready.
