Product Overview
The Outdoor Sleep System is Hangdong International’s high-specification cold-weather sleep solution engineered for mountaineers, alpine campers, and expedition teams operating in low-temperature environments. The sleeping bag is filled with 80% white goose down at 400g fill weight, delivering excellent warmth-to-weight performance with comfort ratings selectable at 0C, -5C, or -10C to match target conditions.
