The Sea to Summit Spark SP3 Sleeping Bag has a 10D nylon shell and 850+ Loft European Goose Down that is so light and compact even ultra-lightweight adventurers can sleep warm at night.

At just 625g for the regular length bag, the Spark SP3 has a perfect all-season balance between warmth and weight 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 SP3 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, 3D hood and a sewn through baffle construction to create a lightweight bag for minimalist adventures in all but the coldest of climates.
