Sea to Summit Spark Women's -9C Down Sleeping Bag Regular pewter grey

Women's-specific cold-weather sleeping bag built for serious performance at minimal pack weight.

The Sea to Summit Spark Women's -9°C is a mummy-style sleeping bag shaped to a women's-specific fit — narrower at the shoulders and wider between the hips and knees to accommodate a natural side-sleeping position. RDS-certified 850+ fillpower goose down with non-PFC Ultra-Dry Down treatment provides reliable insulation, while full box baffle construction locks in warmth across the -9°C comfort rating. The 10D nylon shell and liner keep the overall construction ultralight and breathable.
