Ultra-light and technical sleeping bags that keep you warm, without weighing you down.
Sea to Summit's Spark Series spans everything from an ultralight liner to an expedition-weight mid-winter bag.
The impressive performance is the result of a combination of premium materials and careful design. The RDS 850+ Loft premium goose down, light-gauge #3 YKK right-hand zip and high-performance 10D Nylon shell and 10D lining fabrics, set the stage for superior performance. These materials are combined with a contoured mummy design for efficient insulation, and that mummy design is then tweaked for each model to fit the use scenario best.
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. All Sea to Summit Down Sleeping Bags use Responsible Down Standard (RDS) certified down. The ULTRADRY Down protection also makes the Spark an impressive hard-alpine or adventure racing bag, where every gram is counted.
