Source: montbell.com (verified 2026-07-10) · corroborated by montbell.co.uk. The source page (montbell.com/us product 1121401) is the exact regular "Seamless Down Hugger 800 #3" — distinct from the #3 Long (1121408), Women's (1121414), and Half Length (1121417) siblings — and its embedded spec feed states 800 Fill Power EX Down, headline temperature 30°F (ISO comfort 39°F/4°C, lower limit 30°F/-1°C), bag weight 531 g (1 lb 2.7 oz) / 555 g with stuff bag, a 10-denier Ballistic Airlight nylon taffeta shell, and packed size Ø5.1 x 10.2 in. The corroboration page (montbell.co.uk, the exact "Seamless Down Hugger 800 #3" Khaki / Left-Zip listing at £290.00) independently confirms the 531 g weight, 800 fill power EX Down, Ballistic Airlight taffeta shell, the ISO comfort/lower-limit rating, max user height 6 ft / 183 cm, and 2-way right/left mating zips — though it lists a 15-denier shell and a 568 g "Features" weight, minor distributor discrepancies versus the US manufacturer figures used here. No verbatim US MSRP was fetchable (US price is JS-rendered), so priceUsd is null; shape is null because neither page states "mummy" verbatim.
