Description
New for 2019, the Flame is the women’s series of Sea to Summit’s award-winning Spark sleeping bag, designed to be the pinnacle of lightweight warmth for any conditions – an ultralight down bag for travellers, adventure racers and minimalists of all persuasions. The women’s model is wider at the hip and narrower at the shoulder, and contains more down to reflect most women’s generally colder sleeping temperature.
The Flame FmII uses the highest possible quality of responsibly-sourced down, 850+ loft, Ultra-Dry water repellent European goose down, and an ultra-thin 10D nylon shell. It’s no slouch in the design department either: the contoured mummy shape, full hood and draft tubes (zip, neck & hood) conserve heat efficiently, and vertical chest baffles prevent migration when horizontal. At 890g this has to be the lightest -17°C bag in the world. All this and it fits in a 3.3 litre bag! Comes with compression sack and storage cell.
