Ultralight White Goose Down Envelope Sleeping Bag with Hood Cap – Extreme Cold Rated -10°C to -20°C (210×80cm)

When temperatures plunge and the stakes are high, the Ultralight White Goose Down Envelope Sleeping Bag delivers. Filled with premium white goose down and rated for extreme cold from -10°C to -20°C, this bag is engineered for serious winter camping, high-altitude expeditions, and sub-zero adventures. The integrated hood cap adds critical warmth at the head — the area where most body heat is lost — while the envelope design provides more room to move than a traditional mummy bag.

Available in five fill weights — 400g, 600g, 800g, 1000g, and 1200g — and four colour options, you can dial in exactly the insulation level your conditions demand. At 210 × 80 cm, it fits adults up to 1.8 m comfortably, and the splicing zipper lets you connect two bags for a double configuration.
