Sea to Summit Spark Women's 7C Down Sleeping Bag Regular pewter grey

Women's-specific ultralight mummy bag built around 850+ fillpower down for three-season performance.

The Sea to Summit Spark Women's 7°C is designed for women who require minimal pack weight without compromising thermal comfort. The women's-specific mummy cut — narrower at the shoulders, wider from hip to knee — accommodates a natural side-sleeping position. RDS-certified 850+ fillpower goose down with non-PFC Ultra-Dry Down treatment delivers reliable insulation, while a 10D nylon shell and super-breathable liner keep the overall weight low.
