Worn as an ultra-technical mid-layer or a stylish standalone, the Furnace Hooded Insulator Jacket delivers sauna-level warmth without turning you into a human sleeping bag. Engineered using our 3D weaving technology, baffles are seamlessly integrated into a single continuous piece of fabric—forming the entire puffer in one layer. This cocoon-like architecture, paired with ultra-premium 850FP goose down, provides instant warmth in a feather-light, packable design you’ll wonder how you ever lived without.
