Sea to Summit Flame FmII Down Sleeping Bag - Womens (+2C)
This item is currently not available.


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. The wider mummy shape between hips and knees allows you to sleep in a natural position without compressing the down insulation and creating cold spots. The bags shorter overall length and narrow shoulder girth helps reduce dead spaces and increase thermal efficiency
