The Sea to Summit Spark SP1 Sleeping Bag has a 10D Pertex nylon shell and 850+ Loft European Goose Down that is so light and compact even ultra-lightweight adventurers will be shaking with excitement.

At just 348g for the regular length bag, the Spark SP1 probably weighs less than your evening meal and compresses down so small that Sea to Summit had to re-engineer their compression sacks to reduce effectively.

Utilising Sea to Summit's Ultra-Dry Down fill means the Spark SP1 Sleeping Bag will not wane in performance should it succumb to moisture. A 1/3 length light gauge zipper combines with a close-fitting mummy design, foot box and 3D hood to create a lightweight bag perfect for spring/summer adventures or as a liner to increase the warmth of your existing bag.
