The sheet is sized to fit your mattress and the quilt is sized to fit you.
Locate your height on the ruler below to see which size quilt and sheet/mattress we recommend. 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. The chart below is based on the average weight for each height. Also note that if you are an "active" or "wide" sleeper (i.e. someone that moves around a lot), 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 because it is always free to wrap snuggly around you. Bigger is always more comfortable and just as warm.
Questions? We're happy to help. Let us know your height, weight, and general sleep style and we'll help you find the right size for you.
The sheet is sized to fit your mattress, whether it's one of ours or your current mattress. Our sheets fit both rectangular and tapered mattresses. Note on 4-inch mattresses: our sheets will fit 4-inch thick mattresses with rounded sides, but they do not work on 3D vertical side wall mattresses that are 4" or greater.
DESIGN UPDATE: We are currently in the process of transitioning our fitted sheets over to an adjustable design to accommodate different mattress lengths. These sheets will be named 20", 25", and 30".
20" sheets will fit mattresses up to 20" x 72" x 3.5"
25" sheets will fit mattresses up to 26" x 78" x 3.5" (including 25x72 mattresses!)
30" sheets will fit mattresses up to 30" x 80" x 3.5"
See measurements for max shoulder/hip/foot circumference of each size Bed, along with the dimensions of just the quilt itself.
Find your Bed on the image below and match it to its recommended Dry Sack size. Don't worry, with the recommended size there will still be room to throw in your Zenbivy pillow and even a down jacket. You can expect your Bed to compress down to about half the size of its recommended Dry Sack. (Ex: 7L compresses down to 3-4L, 10L down to 5L, etc)
With a sheet below you and a quilt above, the Zenbivy Bed is built just like your bed at home. The patented 2-piece design allows for the most comfortable and natural night’s sleep in the backcountry. Unlike the constriction of a traditional mummy bag, enjoy the spacious freedom to sleep in any position you want, in the widest range of temperatures. The Zenbivy Bed's versatility and adaptability are simply unmatched.
The Zenbivy Bed 10º is perfect for colder sleepers or anyone pushing the limits of “3-season”. These beds are WARM! If you are looking for maximum comfort and warmth in your backcountry sleep system, look no further than the Zenbivy Bed 10º.
Includes the fitted sheet, convertible top quilt, and large mesh bag for long-term storage. (Mattress, pillow, and dry sack sold separately)
Purely Semi-Rectangular Quilt — The Zenbivy Bed quilt is purely semi-rectangular. This not only provides full coverage when used flat but this new design completely eliminates the common hour-glassing pinch point issue that other quilts have when the foot box is formed. Rotate and move freely at night without the quilt grabbing and twisting around.
The Kylie-curve™ — The Kylie-curve™ is a 3/4-length baffle-backed drawstring along the top of the quilt. The shortened drawstring length cinches only the center portion, so it softly seals around your neck but leaves the edges loose to either drape at your sides or tuck up into the sheet’s hood to block drafts.
Roomy, Integrated Hood — The wide rectangular hood provides extra space and restriction-free warmth around the head and arms for all sleep positions. The new width of the integrated hood makes better use of rectangular mattresses and keeps the pillow from wandering away in the middle of the night.
Thermally Mapped Baffles — We designed all of our quilts to maximize thermal efficiency, distributing down to provide the most warmth where it’s needed. Smaller baffles minimize down-shift, vertical baffles around the upper body prevent down from sliding, and horizontal baffles on the top of the foot box keep down from shifting with foot movement.
Quality Materials — Zenbivy Beds are filled with premium 700 fill-power HyperDRY™ down. This down uses a natural wax-based compound to make it water resistant. It is durable, fluorocarbon-free, and RDS (Responsible Down Standard) compliant.
Unconventional Lining — Our legendary Pongee fabric is both durable and soft, but most importantly, it has a similar feel to a sheet you would use at home. Bring a familiar kind of can’t-beat-it comfort to camp!
Freedom To Move — Never slide off your mattress again. When the top quilt is zipped to the "wings" of the fitted sheet, the Zenbivy Bed is instantly free to get wider when and where you need it to. Then just as instantly, it "settles" to wrap snugly around you. Goodbye constrictive, twisted sleeping bags...
Convertible Foot Box — The convertible foot box allows you to easily regulate your sleeping temperature. On a cold night, zip and cinch it completely shut to keep your feet toasty warm. Mild evening? Leave the bottom open to allow a cool draft. When it's warm out, simply unzip the foot box and use the quilt as a blanket.

Our patented 2-piece sleeping bag is built just like your bed at home with a sheet below you and a quilt above. Even when fully zipped in, the quilt "floats" above you, letting you sleep in any position and giving you the freedom to move without feeling constricted.
Sleeping hot? Easily kick your arms and legs out or "throw the covers off" to get quick, cooling relief. Cold night? Zip the quilt to the sheet and tuck in under the hood to ensure a draft-free night. The versatility of the Zenbivy Bed allows you to use it in a wide range of temperatures throughout the year.
The baffles are perfectly engineered to maximize thermal efficiency. Smaller baffles position the down precisely where it’s needed and minimize down-shift. Vertical baffles around your upper body prevent down from sliding off your shoulders. Smaller horizontal baffles on the foot box keep down from shifting with foot movement.
The Kylie-curve™ is a 3/4-length baffle-backed drawstring along the top of the quilt. The shortened drawstring length cinches only the center portion, so it softly seals around your neck but leaves the edges loose to either drape at your sides or tuck up into the sheet’s hood to block drafts.

Conventional slippery and thin sleeping bag fabric didn't appeal to us... We wanted to elevate your camping experience and give you something better. Our legendary Pongee fabric makes the Zenbivy Bed feel like pure luxury. It's both durable and soft, but most importantly, it has a similar feel to a sheet you would use at home, bringing a familiar kind of comfort to camp.
Designed for all sleep positions, the Zenbivy Bed sheet features an integrated hood that provides restriction-free warmth for your head. The wide rectangular shape give stomach-sleepers room to fit their arms as well! The hood functions as a cubby to keep your camp pillow from wandering away in the middle of the night.
Zenbivy Beds are filled with premium 700 fill-power HyperDRY™ down. Built for performance, this down uses a natural wax-based compound to make it water resistant. It is durable, fluorocarbon-free, and RDS (Responsible Down Standard) compliant.
Our sheets are designed to fit most standard size mattresses on the market—both rectangular AND tapered styles! They are available in 20x72, 25x72, 25x77, and 30x80 sizes. See our full size guide for specifics on sheet/mattress sizing.
Compression Dry Sacks are sold separately. You can expect your Light Bed (quilt + sheet) to compress down to about half the size of the Dry Sack itself.
We recommend the 15L Dry Sack for all sizes of the Zenbivy Bed 10°
This sleep system changes everything you thought about camping. I love my 10° bed so far. Its warm and roomy. I like to move a lot when sleeping and there's no restrictions to my restlessness. The materials are soft and cozy enough to make it feel like my bed at home.
Im returning it and going to replace it with your ZenBivy 10deg Light Bed 25x77 with the hook system. Once we (wife's Christmas gift) got the original one we bought we quickly realized after taking it out of its mesh bag that zipped up its width was going to be too restrictive even for her 5'4" frame.We also thought it would have the hook system which it does not. The replacement will be more like what I was expecting with my original purchase as far as roominess wise and system wise.
I used to tent camp all the time as a kid, teen, and young adult. Then my back just couldn't handle the bumps in the ground, flat air mattresses, cold mornings, etc. We've been trailer camping for the last 15 years. I've been rock climbing for the last 3 years and started climbing trad routes this year with experienced climbing buddies. I want to do a 3 day trip to a local favorite and knew I'd need to figure out sleeping outdoors to make it happen. After lots of you tube videos, and friend advice I settled on a quilt system and ZenBivy was one of the ones I thought might work for me. It's a lot of money so I was nervous my first night out. Holy cow, it was AMAZING! I even slept through the coyotes howling at 1am (according to my climbing partner). When our alarm went off, I was more than happy to sleep for another 30 minutes. I didn't, but the fact that I wanted to and I felt so rested told me all I needed to know -- the ZenBivy 10deg quilt system was a perfect solution!! Combined with my new air mattress, I had the best night's sleep outside ever. Now my wife wants one and that makes me even more excited. Thanks for a great product, a wonderful night's sleep, and here's to many, many more!!
Great sleep system. I’m going to Yosemite at temps should be 20. I got the Zero quilt … so I’ll let y’all know. Packs down super small. Light. Love it so far
I am currently doing a 3 month motorcycle tour of the US, just completed my first month, I have been in sub zero, up at Mammoth Lakes and temps around 5-6c on average, I am really warm at nights and only sleeping in shorts and T, being a side sleeper I hated my Other bags after a couple of nights, this allows me to move as I want, and I consider the design with the sheet the perfect system for myself, constantly changing sides at night, I am super happy with my Purchase, it’s a good job as I rode at high speed from Las Vegas to California 5 hours to collect it, and had not tested it, I flew my Bike (Jolene) into vegas for my trip, and had to collect the quilt from there warehouse facility, so again I thank them for that. So far the best sleep in a Tent I have had. I got the 10 degree with the sheet, definitely get the sheet it’s awesome.
