Product details: Sea To Summit Spark SpI - Long Down Sleeping Bag Light Grey / Yellow

Ultra-light and technical, the Sea To Summit Spark SpI Long Down Sleeping Bag is designed to keep you as warm as possible while minimizing packed weight and size.

The secret to the impressive performance is a combination of premium fabrics and careful design. The RDS 850+ Loft premium goose down, light-gauge #3 YKK zip and high performance 10D Nylon shell and 7D lining fabrics, set the stage for superior performance. These fabrics are combined with a contoured mummy design for efficient insulation, and that mummy design is then tweaked for each model to best fit the use scenario.

The Ultra-Dry Down water-repellent treatment protects the down from external moisture and condensation from the inside of the bag, virtually eliminating the negative effects moisture has on down. The Ultra-Dry Down protection also makes the Sea To Summit Spark SPI Long an impressive hard-alpine or adventure racing bag, where every gram is counted and down has never been a viable option.
