Sustainable Ultralight Alpine Performance and Warmth
The Helium Down Jacket is the ultimate alpine insulator; ultralight, ruggedly durable, and perfect for layering underneath a shell or worn on its own. Infused with Pertex® Quantum Diamond Fuse Technology, the Helium Down Jacket boasts a durable 100% recycled nylon shell. Pertex® Shield reinforced shoulders and upper sleeves provide a waterproof barrier, ensuring warmth and comfort when the skies are unpredictable, and responsibly sourced 800+ fill power goose-down insulation provides unmatched, packable warmth. Brushed tricot-lined hand pockets, an external chest pocket, and dual internal stash pockets provide tons of storage, and the left-hand pocket even doubles as a stuff sack, making this jacket as packable as it is protective. And the elastic drawcord hem and Low-Pro Binding™ deliver a clean silhouette. Designed as the perfect alpine insulating piece and leaning on responsibly sourced material composition, the Helium Down Jacket is a must-have in every alpinist kit.
