S2S Flame FmIV Regular

The Flame Ultralight Women's Sleeping Bag Series spans everything from an ultralight down-filled liner to a mid-winter fast-and-light sleeping bag. Each model uses premium materials and no-frills design to provide cutting-edge performance for the designed end-use. 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.
