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.

Better than expected

For me was on the expensive side, I am bikepacking (munda biddi trail) needed something that would shed weight and compress weight whilst being warm, this does both. Works better than expected in a Bivvy the condensation seemed to sit on top.

Epic little bag

Small, light and warm makes this a great bag. When compressed, the SP2 fits in my hand! I have used this bag exclusively for the last two winters and I have been more than warm camping below the snow line. The addition of a silk liner makes it all the better for little extra weight and bulk. I am 185cm and the long size is more room than I need but feels perfect for me.

Sea to summit ul spark sleeping bag

Great bit of Kit compresses very small ideal for bike packing when temperatures are around 4-8 overnight
I would recommend a silk liner if your out roughing it to preserve the life of the bag and keep the inside clean also will add a few degrees to the rating

Can you zip two bags together?1 answer

G'day Tamzin,

The Sea to Summit Spark SP2 Sleeping bag, and the Spark range of bags only have a left hand zipper, so you won't be able to zip two together.

Can I add more down to this?1 answer

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.

Compression1 answer

Does this sleeping bag come with the compression sack/bag, or do you have to purchase this separately?

- Leongatha(8 months ago)

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.
