THE MORNING TEST
Why it matters
A good sleeping bag shows up at 6 a.m.
The real test of a sleeping bag isn't the spec sheet. It's whether you wake up rested, not shivering. That's what we design around.
- Honest comfort ratingsWe list the comfort temperature, not just the survival limit, so you know how the bag will feel.
- Warmth where you lose itInsulated hoods, draft collars and zip baffles stop heat escaping at the neck and seams.
- Room to turn overShaped cuts give side sleepers space without cold dead air.

Care & packing
Keep your sleeping bag lofty for years
Insulation only works when it can expand. Three simple habits keep your bag as warm as the day it arrived.
01
Stuff, don't roll
Stuffing the bag into its sack foot-first varies the creases and protects the fill.
02
Air it every morning
Open the zip and let body moisture escape before packing up camp.
03
Store it loose
At home, keep your sleeping bag in the large cotton storage sack, never compressed.
