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.

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 withroundedsides, 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"

Configure the Light Sheet 25º with a Light Quilt to make a complete Light Bed. The hood is insulated with 800 fill-power HyperDRY™ down to perfectly match our Light Quilt 25°. However, its mid-temperature rated hood also makes it the best choice if you want one sheet to pair with multiple different temperature quilts.
Zenbivy Light Sheets are designed to fit most mattresses on the market including both rectangular and tapered styles, but pair it with a Zenbivy Mattress to ensure a perfect fit.
Includes the Light Sheet. Quilt, mattress, and pillow sold separately.
Zipperless Configuration — Each Light Sheet is equipped with perfectly placed hooks so you can configure your Light Quilt to it to best suit your needs. Fully clip in on cold nights or leave it partially open to allow a cooling draft — how you sleep is up to you!
Roomy, Integrated Hood — The now wider, more 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.
Adjustable Strap — The Light Sheet features an adjustable clip strap on the back to keep the sheet snug and secure on your mattress.
Soft Fabric — The sheet is made from the same silky-soft yet durable 20d nylon taffeta fabric as our Light Quilt for a perfect pairing that's smooth against your skin.
Storage Pocket — No more rummaging around your tent in the dark. The handy pocket built into the top of the hood makes it easy to find your phone, watch, or headlamp late at night.

All Light Sheets are compatible with all Light Quilts, regardless of temperature rating or size.
By clipping the Light Quilt to the hinged “wings” of the Light Sheet, it's free to get wider where and when you need it to while preventing any possible drafts from the sides as you move. Then, just as instantly, the quilt "settles" to wrap snuggly around you.
Large Insulated Hood
Tuck in under the sheet's large hood to keep your head warm on cold nights. It's roomy and wide enough to fit the arms of stomach sleepers as well! The integrated hood doubles as a cubby to keep your camp pillow from wandering off in the middle of the night.
20d Nylon Taffeta Body
The Light Sheets are made with 20d nylon taffeta. This 20d fabric is buttery-soft and smooth against your skin. It's more comfortable than sleeping directly on the mattress and, as a bonus, it helps to keep your mattress cleaner for longer!
Lightbed. Regular length, 20", fast footbox, 25F/-4C review:
In a drafty tarptent (SMD 'Dechutes plus' w. 'Serenity net') 10mps gusty scandinavial coastal damp wind at 13C/55F on a Big Agnes insulated Zoom UL (R4.3) - I tested my lightbed for three nights now - and I'm totally happy with everything.
I'm 5'10" and happy with my choise of Lightbed lenght (Regular) Extra length would have been a waste. The fast footbox is easy to find, an retains my feet perfectly. The hook&loop at the footbox was kept open, but I guess I will close it at the lowest temperatures. One night was very warm, and I only kept two hook&loops on one side fixed - worked perfectly in order to keep the quilt in place. I fint the Hook&Loops easy to use. Only tiny challenge is to locate the right hook for the right loop if all of them are open in one side.
The pillow barn is genious. Kept my pillow in place which always annoyed me in the old sleeping bag. With this system I could keep my arms warm when sleeping on my stomach having both arms in the pillow barn around my pillow. Also the pillow barn is comfy for my hands when sidesleeping.
I find that a quilt like this makes it easier and more comfortable to turn on a regular (20") mat, compared to turning in a zipper-bag. Long sheet is easy to attach to the mat and gives access to the vent on my BA mat - for tiny deflation adjustment.
Overall much improved sleep with the ZENBIVY. My biggest challenge now is that I might need to purchase the 10F version for winter :-D
Awesome sleep system but unfortunately the light sheet is very slippery. If not too cold i usually sleep on my side/stomach with one leg straight and one leg bent. This is impossible with this sheet as it is so slippery the bent leg just slips down.
It sounds like our Core Sheet may suit you better. The Core Sheet uses a 50D Polyester Pongee fabric which is not as slick as the Light Sheet's lightweight 20D Nylon Taffeta fabric.

Just finished 7 nights on the Wonderland Trail w/ the ZENBIVY light 25 degree, and I am one happy camper. Most bed-like backcountry sleeping experience I’ve found so far. I’ve used quilts for some time now, but the magic of this system is the integrated hood—it’s just a really well thought out design and it works really, really well. Super cozy, comfy sleeping experience!
