If you’re counting every gram, then the women’s specific Flame Fm0 Sleeping Bag from Sea to Summit is the whisper light solution for warm technical expeditions.

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 for performance without the weight. It’s 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, 7D liner and light gauge #3 YKK zip keeps the weight down. Providing a 13°C comfort rating and a 9°C lower limit, this bag is designed for warm weather or it can be used as a liner to increase the warmth of another bag.

The Flame Fm0 is a women’s specific technical bag that’s perfect for ultra-light summer expeditions or to add warmth to another bag in cooler conditions.
