Sea To Summit Spark III Ultralight -8° Sleeping Bag Long Cream Dark Grey & Yellow

Ultra-light and technical, the Sea To Summit Spark Series sleeping bags are designed to keep you as warm as possible while minimising packed weight and size. The Spark Series spans everything from an ultralight liner to an expedition weight mid-winter bag. While the end usage is very different, they reflect a design ethos of matching weather conditions to the lightest bag possible.

The secret to the impressive performance is a combination of premium materials 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 materials are combined with a broader mummy design and fully baffled construction for efficient insulation. 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. It also makes the Spark an impressive hard-alpine or adventure racing bag, where every gram is counted and down has never been a viable option.
