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.

  • 1/3 length light guage zipper
  • Full three dimensional hood
  • Box foot section

Excellent Sleeping Bag!!

Very compact, lightweight and extremely warm! Bought for hiking conditions where you have to carry everything in and out. This was an excellent choice! All of the Sea to Summit gear we've bought so far has been absolutely fabulous; great quality. I can't recommend Snowys highly enough - every order I've placed has been delivered quickly. Snowys is now my 'go to' shop :-)

I bought this bag for Qld conditions. Yes Qld! It gets cold on the tablelands in winter where I sleep out in a hammock. I use a thin thermal mat and the Spark SP3 keeps me well warm enough.

Great quality materials keep this bag small and light yet its thermal qualities are excellent. The construction utilises baffles to distribute the down evenly and I prefer the shape to fit well.

Snowy's service and price were excellent
