Sea to Summit's Flame range of sleeping bags has been specifically designed for women to provide high comfort and light performance for a demanding range of applications. All Flame sleeping bags are characterized by their ultra-light weight and minimal packing size as well as an excellent thermal performance. The Fame Fm0 is ideal for summer tours. Sea to Summit's quilted construction minimizes weight and ensures that the down stays in place. The Fm0 can also be used as a liner to improve the thermal performance of another sleeping bag. Ultra Dry DownUltraDry Down is a PFC-free water-repellant treatment applied to the down used in all Sea to Summit sleeping bags. UltraDry Down retains over 60 % more loft, absorbs 30 % less moisture and dries out 60 % faster when compared to untreated down – which means the down will insulate better even in damp conditions. The treatment also inhibits bacterial growth, making your bag last longer. UltraDry Down treatment is an environmentally friendly application.
