This is our top choice sleeping bag for Nordic conditions!

Sea to Summit has been improving their Spark series bags year after year. User voices have been heard, and new the new bags have e.g. a longer zipper and wider cut. The bags still have an excellent balance of lightness and features, thanks to the ultralight fabrics. The bags have a 10D shell material and 7D liner material, and top quality 850 cuin hydrophobic down. Light materials result to a small pack size as well. With the weight of 665 g it is lighter than many comparable temperature quilts. Sleeping bags with similar warmth-to-weight ratio are very rare to come by in the market.

The temperature ratings of Spark SpIII are perfect for three-season hikes in Northern climate.

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. The ULTRA-DRY 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.
