The secret to the Sea to Summit Flame FmIII Down Sleeping Bag's impressive performance is a combination of high-quality fabrics and careful construction. The Flame Down Sleeping Bag features a warm 850+ loft 90/10 goose down fill, an extra-light YKK zip, and a shell made from high-performance 10D nylon and 7D lining. These fabrics combined with the contoured mummy shape guarantee efficient insulation and an optimal warmth-to-weight ratio.
The special water-repellent Ultra-Dry Down treatment protects the down from external moisture and condensation inside the sleeping bag, virtually eliminating the negative effects of moisture. This treatment makes the Sea To Summit Flame an ideal sleeping bag for demanding trips where every gram counts.
