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)
If you're someone that mostly car camps, sometimes backpacks, and prioritizes comfort above all else, then this is the sleep system for you. The original Zenbivy Bed with Flex™ Mattress offers maximum comfort and convenience. This bundle includes everything you need for your perfect night's sleep.
Select your sizes/colors. We recommend the 10L Dry Sack & Caps for all sizes of the Zenbivy Bed 25°. Be sure to match the fitted sheet size to the mattress size (20x72, 25x72, 25x77, 30x80).

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.
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.
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.
A purely semi-rectangular quilt not only provides full coverage when used flat but also eliminates the common hour-glassing pinch point issue that other backcountry quilts have when the foot box is formed. Rotate and move freely at night without the quilt "grabbing" you and twisting.
The most comfortable camp mattress ever designed. Our 4-way stretch fabric allows this mattress to “flex” with your shape and movement, so the top feels softer and more supportive than other camp mattresses - even at firm air pressures.
Includes an Inflation Dry Sack for fast, breath-free manual inflation and waterproof storage.
The 2-piece design of the Quilted Pillow makes it superior to other camp pillows. The separate pillowcase is easy to wash and provides enough space to stuff extra clothing items inside to dial-in the softness and height at which you sleep best!
The Zenbivy Bed Bundle includes a Dry Sack and Compression Caps for compact, reliable, watertight compression.
We recommend a 10L Dry Sack for all sizes of the Zenbivy Bed 25°. You can expect it to compress down to about half the size of the Dry Sack itself.
*Fits the quilt, sheet, and pillow. Mattress rolls and packs separately.
