This Sleeping Bag Fits in The Palm of Your Hand

Written by Drew Prindle Posted on March 13, 2014

If you’re anything like us, now that daylight savings time has come, you’re already daydreaming about summer — and more specifically, summer backpacking trips.

Pretty soon all this snow will be gone, and once again you’ll be able to stuff a few provisions in a sack, sling it over your shoulder, and venture deep into the middle of nowhere. But since there’s still a couple months until that happens, all you can do at this point is prepare. It’s time to start getting your gear together.

Over the winter, Sea to Summit dropped a new sleeping bag that you’ll definitely want in your pack come summertime. It’s called the Spark SPI, and it might be the most compact sleeping bag we’ve ever seen. When fully unraveled, it’s the same size as your average bag, but when it comes time to pack up the entire thing can be folded, rolled, and compressed into a ball of sorts that fits right in the palm of your hand.

The secret is Spark’s premium quality 850+ loft goose down and ultralight 10D shell. All together, the shell, lining and other components have a lower combined weight than the down insulation inside: 6.3 oz for the down versus 6 oz for the rest of the bag.

You can snag one on Sea to Summit for around $390, but it can be found for much cheaper elsewhere. Find out more here.

    Compressing a sleeping bag, whether down or synthetic, affects the loft, which of course is what keeps you warm, the ability of the insulation to trap heat, which decreases the insulating value and overall lifespan of the sleeping bag. Keeping your sleeping bag as uncompressed as possible as much as possible is the ultimate goal. My sleeping bag, a quilt actually, is designed, along with the backpack, to take up half of the space in my backpack to reduce compressing it. I cannot fathom the supposed benefits of your new highly compressible sleeping system. What else are you packing that the sleeping bag, one of the absolutely essential items for wilderness survival, needs to be as small as possible.
