The Spark™ Series Bags Are Ultra-Light And Technical 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. Premium Materials and Careful Design 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. Responsible Down Standard (RDS) 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. These bags are impressive hard-alpine or adventure racing bag, where down has not previously been a viable option, and where every gram counts. Responsible Down Standard (RDS) All Sea to Summit Down Sleeping Bags use Responsible Down Standard (RDS) certified down. Mid-Summer Fast Hikes The Spark SPO UltraDry Down Sleeping Bag is Ideal for mid-summer fast hikes or adventure racing.
