The Sea To Summit Spark SpII Regular down sleeping bag is characterized by its ultra-light weight and minimal pack size and excellent thermal performance. 

The Spark SpII features a warm 850+ loft 90/10 goose down fill with Ultra-Dry Down protection from moisture. In addition, the sleeping bag features the extra-light YKK #3 zipper as well as a shell made of 10D nylon and 7D Lining. These materials combined with the contoured mummy shape ensure efficient insulation and one of the
best possible warmth to weight ratio. Vertical chambers on the torso contain an extra amount of down and provide additional thermal performance, while vertical chambers on the chest optimize down distribution and prevent slippage.

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 Spark SpII Regular an ideal sleeping bag for demanding trips where every gram counts.
