Sea to Summit Women’s Flame FMIII Down Sleeping Bag


5.0 (1 review)

Sea To Summit’s new ultralight Flame Series of sleeping bags are specifically designed for women. Wider at the hip and narrower at the shoulder and designed to keep you as warm as possible while minimising packed weight and size.

Engineered for women to provide extra warmth where needed, Flame series sleeping bags are what you reach for when you need a high performance sleeping bag but don’t want to be weighed down by one.

The Flame FMIII combines more overall ULTRA-DRY Down 850+ loft premium goose down, a light-gauge #3 YKK zip, high-performance 10D nylon shell and 7D lining fabrics and a contoured mummy shape for efficient insulation and superior performance.
