Feathered Friends Hummingbird UL 30 Sleeping Bag

The Hummingbird UL 30 is the lighter sibling of the UL 20 within the same mummy-bag line — using the same 950 fill-power goose down but in a smaller 323 g charge, it drops to 611 g total weight with the lower limit shifting to -1°C. The shell remains Pertex Endurance UL 10D nylon ripstop, with a DWR-treated 15D nylon ripstop liner. Unlike the men's-specific UL 20, this bag is cut unisex, giving it a broader fit across body types regardless of gender. Shoulder (145 cm), hip (135 cm), and foot (104 cm) dimensions match the standard regular size rated to 182 cm. Packed volume of 8 liters is slightly lower than the colder variant, a direct result of the reduced down charge. The full-length left-side zip is two-way, a draft collar and draft tube limit heat loss, and the hood is anatomically contoured. The down carries RDS certification. The package includes both a stuff sack and storage sack — standard equipment for the brand even on this pared-down model built for warmer three-season use and fast, minimal-load travel.
