Feathered Friends Hummingbird UL 20 Sleeping Bag

The Feathered Friends Hummingbird UL 20 Sleeping Bag is a classic hooded mummy bag rather than a quilt from the Flicker line, offering full body enclosure and better insulation for more extreme conditions. It's filled with 399 g of 950 fill-power goose down inside a DWR-treated Pertex Endurance UL 10D nylon shell with a Flite 15D ripstop liner. The -7°C lower limit and -4°C comfort rating give a more realistic picture of when the bag actually stays comfortable to sleep in. The cut is men's-specific, following typical male shoulder and hip proportions — fit may differ for women or anyone with a different build compared to the brand's unisex models. At 687 g for a full mummy construction with hood, collar, and draft tube, it's remarkably light for this level of insulation. The full-length left-side zipper is two-way, and the hood is adjustable and anatomically contoured. The down carries RDS certification, and the bag is made in Seattle. Both a stuff sack and storage sack are included.
