If you’re searching for a compact and efficient sleeping bag for performance when every gram matters, then the Flame Fm1 from Sea to Summit is the ultimate choice.
This bag has a contoured mummy design which is wider at the hips and narrower at the shoulders for a women’s specific fit. The Flame is constructed from premium materials and is filled with RDS 850+ Loft premium goose down which has a water-repellent treatment to protect it from condensation and external moisture.
The sewn through box baffle construction keeps the down in position without adding extra bulk, while the minimal 10D nylon shell and 7D liner and light gauge ½ #3 YKK zip doesn't add unnecessary weight. Providing a 9°C comfort rating and a 4°C lower limit, this bag is designed for warm or mild conditions.
The Flame Fm1 provides performance without the excess, so you can sleep comfortably on your technical expeditions.
