On fast and light trips in cooler conditions, the Flame Fm3 will keep you comfortable while you sleep without the excess weight.

The Flame has an expedition mummy bag size to give you extra room and is shaped to be wider at the hips and narrower at the shoulders for a women’s specific fit. Featuring a lightweight 10D nylon shell and 7D liner, this bag also has a full zip with two sliders so you can access it easily and ventilate if necessary. It’s filled with RDS certified 850+ Loft premium goose down with an ULTRA-DRY water-repellent treatment to protect it from external moisture and condensation.

The full box baffle construction helps reduce cold spots and accommodates the extra down while the vertical baffles on the chest prevent it moving around. To minimise heat loss, there’s also a hood and front neck draft collar and zipper draft tube. Providing a -4°C comfort rating and a -10°C lower limit, this bag is designed for chillier conditions.

For a reliable sleeping solution on minimalist expeditions, you can rely on the Flame Fm3 Sleeping Bag from Sea to Summit.
