Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


Nemo’s award-winning Sonic is updated to make a good bag better, with a few extra features to ensure you get a great night’s sleep. A redesigned collar and hood seal out cold and retain warmth where you need it. Stretch stitching at the knees maximizes internal volume and make side-sleeping easier in this form-fitting mummy bag. Thermo Gills™ allow you to dial-in the perfect temperature when you're warm, but the air outside is too cold to unzip – like cracking a widow. Overstuffed with 800 fill-power hydrophobic down to offer serious warmth in serious weather.
