Verified directly from westernmountaineering.com: 20F rating, 850+ FP premium goose down, mummy, 6'0" weighs 1 lb 13 oz (1.81 lb), packed size 7x13 in, left or right zipper, price $640-$685 across lengths. Weight listed is for 6'0". Corroboration URL updated to Backcountry listing. The corroborating page this record cited (https://www.backcountry.com/western-mountaineering-ultralite-super-sleeping-bag-20-degree-down-wes0031) is gone: on 2026-09-11 it answered 200 and redirected to https://static.backcountry.com/eu/bc_eu.html, both from a residential connection and from a datacenter on another continent — so the page is gone rather than withheld from one asker. This record therefore no longer claims an independent second witness for its figures. The page the figures were read from, westernmountaineering.com, still answers.
