The Sea to Summit Spark II is an ultra-light and technical down sleeping bag, designed to keep you warm whilst minimising packed weight and size.
Offering an excellent fit whilst providing extra warmth, the Sea to Summit Spark II is a high performance yet lightweight sleeping bag. With a comfort temperature limit of -2*C, the Summit Spark II utilises a sewn through construction (which minimises weight) and vertical baffles on the chest to maintain down positioning for heat reflection. The updated sizing provides extra room for shoulders and hips without compromising thermal efficiency and a 1/2 zip aids access and ventilation. This bag is ideal for mid-summer fast hikes or adventure racing.
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 contoured mummy design for efficient insulation, and that mummy design is then tweaked for each model to best fit the use scenario.
Sea to Summit's 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 and down has never been a viable option.
