Being cold while camping sucks. And carrying a heavy sleeping bag on winter camping trips can be equally as infuriating. For years I’ve been a cheapskate with certain camping gear; opting instead to use money for ski gear and trips, neglecting certain necessities for the few times a year they’re needed. My heavy and old sleeping bag was one of them, one that has been carted into lean-tos, yurts, and campsites while I bitched the entire time. I waited too long to replace it with the Sonic 0 Down sleeping bag from Nemo: a two-pound bag that keeps me warm, and doesn’t ruin my approach.

I picked up the Sonic bag last winter, having planned a couple yurt trips including one to a remote cabin with a monster slog home after being heli dropped in. It was the promise of those trips that deterred me from re-using my old bulky bag. The dirtbag in me fought the change, but the practically of it made me swap to this bag that weighs just over two pounds and packs down to a cylinder size of 18-by-11 inches, coming stock with a cotton storage and drawstring stuff sack.

The Sonic 0 Down has won several accolades from backpacking publications, so I knew it would be great to throw in a tow sled while skinning and could be stashed away if I had to place it in a big pack. Featuring 850 of down fill with patented Thermo Gills, allowing the bag to regulate temperature without letting drafty cold air in, it maintained warmth without inducing heat stroke while rolled out next to a cranking wood stove. Better yet, it’s comfortable, even while I tossed and turned falling asleep—a product of the stretch construction at the lower section of the bag. Additional features were a 20D Nylon Ripstop with DWR shell fabric, a comfortable mummy hood, easy to access zippers, and a waterproof and breathable foot box at the bottom of the bag—having experienced some gnarly frostbite in years’ past this feature was well thought out.

Consistently since the first trip, the bag has performed wonderfully and has been even keel on its temperature regulation in cold environments. After multiple hut trips, truck camping in Montana, and backpacking in the Wind Rivers of Wyoming, the bag has been awesome. It isn’t the cheapest, but it is worth the equity investment. Because what good is being off the grid when you’re cold and tired?
