North Face One Bag: first impressions

Like a 3-in-1 jacket, North Face’s One Bag sleeping system has interchangeable layers to configure it for 4°C/40°F, -6°C/20°F or -15°C/5°F temperatures (see: Sleeping bag temperature ratings explained). When you’re road-tripping, camping, or backpacking – whatever the season – the One Bag’s multiple layers combine to keep you warm.

Use the lightweight synthetic outer layer solo on warm summer nights. And then add the 800-fill down mid-layer when the mercury dips. Want to take this bag winter camping? No problem – just use all the layers and the bag will keep you toasty even when it’s down to -15°C/5°F outside.

The zippers are color-coded and user-friendly, so it’s easy to add a layer without getting in a tangle. And when you don’t need full insulation, the rolled-up bottom layer makes a great pillow, and the midlayer converts to a shawl for hanging out before it’s time to tuck in.

North Face One Bag: in the field

Having a single bag to get me through four seasons of camping has a lot of appeal. This bag offers that option cleverly, with three layers that can be combined in several configurations, which lets me sleep comfortably in a broad range of temperatures.

One of the things I loved about the design of this versatile bag is that, any layers I wasn’t sleeping with converted to into a useful accessory. The mid-layer has a neck snap to turn it into a shawl. Stuff any unused layer into the compression stuffsack turned inside out, and voila! You have a fleece-lined and a cozy pillow.

I worried that adding more warmth would be hard if I crawled into my One Bag then decided I wasn’t warm enough. But the zippers are color-coded and user-friendly. It only took a couple of seconds to layer or de-layer as needed.

One other thing that impressed me about this bag: the midlayer had a draft collar and draft tube, while the other layers didn’t need their own. Hang loops let me air the layers.

On the downside, there were no stash pockets. Overall, this bag has a bigger/less technical fit, and it’s not the lightest (but of course you can tailor it to the conditions you expect to encounter).

Overall it is a superb, multifunctional sleeping bag for the camper who likes to explore in a variety of conditions and across all four seasons, and a worthy inclusion on our list of the best sleeping bags for 2021.
