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)
New sheet sizing! Please see the Specs + Materials tab for sizing details.
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.
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! 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 10L Dry Sack for all sizes of the Zenbivy Bed 25°
I love the versatility of the whole set up. It's great being able to kick the covers off when I get too hot or get all snuggled up with it's super cold. I was stunned by how warm it kept me! And the pillow holder ... I didn't realize what an awesome thing that was until the first time I used it. My pillow didn't slide all over the place when I changed positions during the night!
This bed is amazing! Packs small, light weight, super warm! The inside material is so comfortable and soft like sleeping in your best sheets. Plenty of room to move around but it doesn’t let in cold air. I’ve tried a ton of different camping options and this is by the far best I’ve ever used. Perfect for bikepacking and backpacking. I went with the large quilt. I’m 5’11 and 180 pounds.
I didn't know how badly my partial nights of sleep on trail impacted me until I got real sleep. I paired this with my big agnes q-core, & used it for two weeks on the CT & CDT, with temps down to 35ish. Best tent sleep ever. No more waking up all twisted & knotted in a standard bag, half off my sleep pad, wondering where my pillow went. I don't need as much to keep me warm as some, but I would definitely use this down to it's 25 rating without hesitating. One small critique: mid-section being unsealed creates airflow, which I actually liked most of the time, but wished I could have stopped easier when the temps dipped. I might try to solve this on my own with a few small squares of velcro for next time. Overall, I'd highly recommend.
Thus far I have used the Zenbivy bed 25 for about 2 weeks in total. I'm planning on using it for through hikes coming up and over the course of the winter. This is my main bed am I traveling and off grid living. I got the larger mattress which I'm happy with because I'm 6 ft 3 even though it's slightly heavier. My only real gripe is how warm it is. A summer sheet would do it wonders. Also I wish the coloring was black or blue mostly black. But other than that that's an excellent sleep system.
The 25 degree bag served me well on the high Sierra trail in August. We Slept under the stars at Guitar Lake the night before submitting Mount Whitney. Glad I made the switch away from my mummy.
