The Sea to Summit Spark SP2 Sleeping Bag has a 10D 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 464g for the regular length bag, the Spark SP2 will be one of the lightest pieces of gear in your pack 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 SP2 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 perfect for lightweight spring/autumn treks, adventure racing or cycle touring.

G'day Tamzin,
The Sea to Summit Spark SP2 Sleeping bag, and the Spark range of bags only have a
I bought this bag a little over a year ago, and Ive used it several times over winter, I feel like im not quite warm enough when it gets town to 3 or 4 degrees. Ive got a sea to summit extreme liner, which does not add 15 degrees of warmth, maybe 3 at most. I've got about 300g of down, wondering if its possible to add it, are the baffles made large enough to take extra down? when i hold the bag up to the light, its pretty easy to see through the baffles around the seams.
G'day Clint,
There's definitely enough space in the baffles of the Sea to Summit Spark SP2 Sleeping Bag to add some down to the bag. Just keep in mind that doing some DIY work on the sleeping bag might mean that there are a couple of extra hoops to jump through if you need to make a warranty claim at any stage.
Does this sleeping bag come with the compression sack/bag, or do you have to purchase this separately?
G'day Ben,
The Sea to Summit Spark SP2 Sleeping Bag comes with a compression bag, so you won't need to grab one separately.
