Source: featheredfriends.com (read 2026-07-10) · corroborated by cleverhiker.com (read 2026-09-21). Fetched the featheredfriends.com product page for the Swallow UL 20/30 (Shopify handle ...swallow-ul-ultralight-20-30-degree-down-sleeping-bag-c0); its 20 Degree / Regular variant is the exact "Swallow UL 20" model, priced $659.00 (Flame), with the manufacturer spec table confirming a 20ºF rating, 950+ fill power goose down, mummy (medium width) shape, Left Side #5 YKK zipper, Average Weight Reg 1 lb 10.6 oz / 754 g (1.66 lb), and 9 L packed size. All spec values were extracted verbatim from that page; the two-capacity/two-length spec rows were disambiguated so the 20 Degree Regular figures were used (fill weight 1 lb 0.8 oz, average weight 1 lb 10.6 oz, 9 L). CleverHiker's dated review independently corroborates the $659 price, 950+ fill power, 20°F rating, 1 lb 10.6 oz weight, and mummy shape, confirming both price and model identity.
