Locate your height on the ruler below to see which size quilt and sheet/mattress we recommend for you. Ideally, you'll want to fall somewhere in the middle of the range. If you find yourself in the yellow, you'll probably want to size up for the most comfortable fit. Please note that the chart below is based on the average weight for each height. If you are an "active" or "wide" sleeper, you may want to consider sizing up to allow yourself more space to sleep naturally.
When in doubt, size up. Unlike mummy bags, there is no thermal disadvantage to a larger size Zenbivy Bed because it is always free to wrap snugly around you. Bigger is always more comfortable and just as warm. Questions? We're happy to help. Send us an email with your height, weight, and general sleep style and we'll help you find the right size for you.
The zipperless design of the Light Quilt gives you the weight of a closed foot box quilt, with the full-flat functionality of a convertible quilt. Zenbivy’s buttery soft 20d fabrication sets this quilt apart from its more “purist” 10d competitors. It is the softest and most durable legitimately ultralight quilt out there. Premium 800 fill-power HyperDRY™ down rounds out the package and delivers a final quilt that is weight competitive with much more expensive offerings while delivering on Zenbivy’s promise of maximum comfort.
Add a Zenbivy Light Sheet 25° to create a complete Bed for even more comfort options.
Includes the Light Quilt and a large mesh bag for long-term storage. Dry Sack and Compression Caps sold separately.
Quality Materials - We use premium 800 fill power HyperDRY™ fluorocarbon-free water-resistant down from Allied. This is the best down you can get. It is sourced according to the Responsible Down Standard and each quilt comes with a tag that allows you to track exactly where your down came from.
Zipperless Versatility - The patented zipperless foot box design is every bit as secure as a zippered foot box, without the weight of zippers. It forms using a few simple hooks and loops, with a snap and a drawstring to easily regulate your sleep temperature. Sinch the bottom closed on cold nights, or loosen it to allow a cool draft or unhook it completely to use it flat like a blanket on warmer nights.
Unconventional Fabric - Most ultralight quilt makers shed weight by making their fabric a thin and clingy 10d. We opted to find clever ways to ditch ounces while keeping the fabric a very soft, comfy, and durable 20d. 20d fabrics are much softer than traditional ultralight technical fabrics while only being a fraction heavier.

Love, love, love it! I wish I would’ve known about the Zenbivy system sooner. The material is soft and quiet, I am able to turn side to side without getting all twisted up as I would in a mummy bag. Once you get used to setting it up, it’s a breeze!
had to buyvmy wife one cuz she loved mine so much. has not let me down
The design of this sleep system is really amazing. I tried it out at home and was really impressed by the functionality/versatility and was super excited to use it on my trip to Thousand Island Lake in the Eastern Sierra.... like very excited. However, when I got out there the night before I'd hike up into the mountains I woke up cold and it was only 40 degrees outside, which I figured a 25 degree quilt could have handled. I actually checked my thermostat because I was surprised by how cold I felt, but it read 40 degrees. I had the foot box completely cinched up and all of the loops clipped down, which I believe the warmest configuration. There was a little draft around the neck area, which is expected with a quilt, but the interior surface of the quilt was cold to the touch, even where the quilt was completely draft free. I consider myself somewhere between a warm/cold sleeper, I was fully clothed with long underwear/socks and an insulated jacket, and was using a 6.9 r-value sleeping pad, yet I still woke up cold. So much so that I decided to cancel that actual backpacking portion of the trip because I didn't think the quilt would keep me warm enough in the mountains where I was expecting lows of 33 degrees. It was really disappointing. Perhaps a liner will help mitigate the cold interior surface but I wish I would have gone with the 10 degree quilt.
Where have you been my whole backpacking life! I am a hot sleeper and traditional mummy bags are suffocating. The first night I slept in my zenbivy light I said to my husband that I felt like I had been set free! Not only is this lighter than my mummy bag, it compresses smaller, is perfectly suited for me to sleep without overheating yet able to close up if it’s colder outside. I am truly in love with the zenbivy sleep system
The quilt was very warm during my first use of it. I recently stayed in Yellowstone with lows hitting the mid 30s. I tend to sleep warm anyways, but felt comfortably warm each night.
