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

Women's-specific mummy bag engineered for ultralight backpacking where thermal efficiency and packability are priorities.

The Sea to Summit Spark Women's 7°C Down Sleeping Bag uses a women's-specific body map — narrower at the shoulders and wider between hips and knees to suit a natural side-sleeping position. RDS-certified 850+ fillpower goose down with a non-PFC Ultra-Dry Down treatment provides reliable insulation, while a 10D nylon shell with PFC-free DWR and a highly water-repellent hood and footbox resist moisture ingress.
