The versatility of the Flame Ultralight Women’s Sleeping Bag Series spans from an ultralight down-filled liner to a mid-winter fast-and-light sleeping bag. Each model uses premium materials and design to provide cutting-edge performance.

The women’s specific mummy fit is narrower at the shoulder and wider at the hip, and features extra down compared to the unisex Spark models.
