Product Highlights

The innovative Sierra Designs Backcountry Bed 600F 2-Season zipperless sleeping bag provides campers with similar comfort to their beds at home whether they’re back, side or stomach sleepers. Featuring 600 fill duck DriDown water-resistant down and strong polyester ripstop shell fabric, the Backcountry Bed 600F 2-Season is a high-quality, comfortable bag for warmer weather that won’t break your budget.

Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of down have an incredibly soft, comfortable feel, and despite advances in synthetic materials, continue to provide the best warmth-to-weight ratio of any insulation available. The one inherent weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet, but the DriDown featured in the Backcountry Bed 600F 2-Season bag performs differently. Employing a unique, innovative polymer application, DriDown actually creates a hydrophobic finish on each individual plume of down. This treatment results in insulation that stays dry up to 10 times longer and dries 33% faster, should it become wet, than untreated down bags.

By eliminating zippers, Sierra Designs has created a sleeping bag that’s more similar to your down comforter at home than a traditional sleeping bag, though without your comforter’s annoying ability to shift off your body in the middle of the night as you move. Get in the Backcountry Bed through the unique catenary shaped opening that’s smaller than bag width to seal out drafts even when you’re shifting inside. Once settled in, the versatile integrated comforter fits naturally around you and conforms to your preferred sleeping position while also allowing you to easily adjust for varying temperatures. Insulated pockets in the comforter provide a cozy place for your arms and hands to stay warm if you’re not cocooned down inside the bag, or tuck the sides of the comforter around and beneath you when the temperature drops to be fully ensconced; the top of the bag also allows you to tuck your head inside for insulated warmth much like a hood. A unique zipperless foot vent allows you to extend your feet out of the bottom of the bag in balmy weather but effectively retains heat when temperatures require it.

Beyond the zipperless construction, the Backcountry Bed 600F 2-Season has no additional cords or Velcro to get in the way of comfort, though it does feature a sleeping pad sleeve on the bottom to allow you to even better create a bed-like sleeping experience while spending the night outside.

The Sierra Designs Backcountry Bed 600F 2-Season sleeping bag is available in Regular (fits up to 6' 0") and Long (fits up to 6' 6") sizes. A stuff sack and storage sack are included.

Sizes available: Long, Regular

  • Christopher F. Kingwood TX

    Likes: Very comfortable and warm. Feels more like being in a bed than being in a sleeping bag.

    Dislikes: Not as compressible as one would prefer, but not bulky by any means.

  • Nathan J. Huntsville AL

    Likes: I did a lot of research on picking out a new sleeping bag and ultimately settled on the Backcountry Bed because of the unique zipperless design. I like light gear, but I'm not an ultralight fanatic and still value comfort and functionality.

    First, it is capable of holding in the warmth. At 6'1" I purchased the long bag and stayed plenty warm in verified temps in the mid 20's degrees F with baselayers. Even when rolling from my back to my side I did not experience any cold air intrusion, which was one of my initial concerns. Second, the ability to regulate temperature is incredible. Not only is the quilt nice, but the foot vent is great and worked just like advertised.

    Dislikes: I would prefer goose down over duck, but I understand this is a first gen product and I'm sure they are holding that for future releases. The weight and pack size are okay, but not amazing. After a full week trekking in Nepal to break the new bag in, I really have not found any substantial downsides.
