Spark SpIV Sleeping Bag -15°C
The Sea To Summit Spark SpIV Sleeping Bag is ultra-light and technical, the Spark™ Series bags are designed to keep you as warm as possible while minimising packed weight and size. With top quality 850+FP down and a cozy mummy bag fit, the Sea to Summit Spark SpIV -15°C Sleeping Bag is one of the warmest sleeping bags we've seen for under 1kg. EN Rated to -15°C, this ultralight sleeping bag is suitable for year round use. The Spark IV also comes in a longer length, perfect for tall hikers.
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.
