A thoughtfully designed bag with a mix of practical and innovative features designed to offer enhanced comfort and performance in real world conditions.
- Internal stash pocket
- Comparatively heavy
Although the Deuter Exosphere -10, like all other Deuter’s Exosphere bags, has a slimline appearance, it's much roomier than it looks. That’s thanks to elastic seams that means they stretch up to 25% in width for added comfort. This also makes them more thermally efficient by eliminating dead space.
The generous amount of synthetic fill, snug collar, ergonomic hood, zip baffle and extra-thick padded footbox all make for a toasty bag that is ideal for cold sleepers. The women’s SL version even has additional fleece zones to ward off chills.

Other clever innovations include reinforced water-resistant panels to help protect the bag from damp, ideal if you use a bivvy bag or if you often wake up to find your head and feet touching the walls of your tent.

When you first climb into this bag, its elasticated chambers result in a slightly unusual body-hugging sensation that feels strange at first. However, it is very warm, making it ideal for cold sleepers.
The zip runs smoothly and doesn’t snag, even on the chunky full-length baffle. There’s also an inside pocket for stashing camera batteries or a smartphone, a useful feature that is often neglected.
Note that if you’re over 6ft tall you’ll struggle to fit in this bag, so go for the recently released long-length version (not available at time of testing). The other drawback is that it is relatively heavy and bulky when packed. Not a problem, of course, if you’re car camping, so this is a great bag for use on a campsite.
