Down Kick

"The ultralight and technical Spark sleeping bags are designed to keep you as warm as possible with reduced pack weight and size. The Spark range ranges from an ultralight liner to an expedition winter bag. Although the uses are very different, the design philosophy reflects the lightest possible bag. The secret to the impressive properties is a combination of premium materials and thoughtful design. RDS 850+ Loft premium goose down, 10D nylon outer fabric and 7D inner lining lay the foundation for superior properties. These materials are combined with a contoured mummy design for effective insulation, and the mummy shape is then adapted to each model to best suit the use scenario. Our ULTRA-DRY Down water-repellent treatment protects the down from moisture and condensation from the inside of the bag, which almost eliminates the negative effects of moisture on the down. All Sea to Summit down sleeping bags use down certified according to Responsible Down Standard (RDS) ULTRADRY Down protection also makes the Spark an impressive alpine or adventure bag, where every gram counts, and down has never been a realistic option. NB! Not designed to be connected to another bag." • Ultralight 7D fabrics for minimal weight and pack size • RDS 850 + Loft Premium Goose ULTRA-DRY Down for maximum insulation value • Sewn-through construction for low weight • Updated size compared to previous model provides extra room for shoulders and hips while preserving the insulation properties • Contoured mummy shape for comfort and effective insulation • Materials: Outer fabric: 100% nylon, lining: 100% nylon, primary filling material: goose down (at least 90% down), packing bag: 100% nylon • Includes removable pack bag attached to foot end for compact storage • Half zipper with single slider facilitates access while keeping weight to a minimum • NB: Not designed to be paired with another bag
