Sea to Summit Flame Ultralight Women's Sleeping Bag 48

The Flame Ultralight Women's Sleeping Bag 48 is a pure summer bag, rated to a comfort temperature of 9°C with a limit of 4°C and an extreme rating of -10°C for margin only, not planned use. At just 350 g it is the lightest bag in the Flame range, built around a minimal 190 g fill of 850+ fill-power hydrophobic goose down (90/10) held in place by sewn-through vertical baffles — a simpler, lighter construction than the box baffles used in colder Flame models. A half-length, right-side zipper and 10D nylon shell keep weight down further, while a draft collar limits heat loss at the neck despite the pared-back design. A stuff sack is included. The women-specific cut — wider hip, narrower shoulder — fits users up to 170 cm. This bag targets warm-weather backpackers, summer thru-hikers, and anyone building a minimal base-weight kit for three-season trips who can layer up on genuinely cold nights.
