This Sea to Summit sleeper pushes the limits in the world of weight to warmth.

Packed with the finest goose down, the SPIII Sleeping Bag from the Sea To Summit Spark Series offers unbelievable warmth when compared to its less-than-700-gram weight. It’s packable too, so a great choice if you’re headed on long backpacking trips or cycle tours. When moving towards colder nights, it works as a great liner bag.

The perfect bag for summer adventuring

The SPIII compresses like a dream – Ideal if you’re trying to stay light on your feet during the summer months. The Ultra-Dry Down has 850+ loft will give you plenty of warmth and guarantee a dry night’s sleep too, without being overly bulky.

All about that warmth to weight ratio

As well as the high-performance down, you get even more warmth-to-weight thanks to the cleverly engineered third-length, light-gauge zip and microweight shell and liner fabrics. The bag is close-fitting, so really gives you that cosy cocoon feeling, with a full hood and footbox that fit neatly to keep weight to a minimum.

Bafflingly clever design to seal in your warmth

Constructed with box wall baffles, the Spark III offers heat retention throughout, with a draft tube over the zip to eliminate cold spots. Around the neck and head, the baffles are enlarged to trap warmth and achieve a lower limit rating of 4°C.

Space-age looks and next-level bag tech – this Sea to Summit sleeper is a winner with us.
