From the towering summit of Kilimanjaro to rugged Himalayan trails and frosty days in mountain villages, it's relied upon for its unparalleled warmth and protective features as temperatures plummet. Featuring 296g of premium down fill in a size large, it delivers essential insulation in the harshest conditions while maintaining the versatility needed for prolonged expeditions through swiftly changing weather. Our down is responsibly sourced and conforms to the rigorous standards of the DOWN CODEX®, ensuring ethical procurement through meticulously monitored supply chains.
