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 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)
NOTE: For help with sizing, please see the Specs + Materials tab
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.

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.
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.
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!
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.
This sleep system is pure genius. I'm recommending this to all my hike & camp fiends. Heck, even to my hike & camp enemies! It's THAT good! Super comfy & warm with tons of adjustments to fit your needs in the woods. Worth every penny!
I own the Light Quilt in 10 and 25 degree, the Light sheet in 25 degree, and the core sheet. The ability to mix and match each piece is perfect for my use and Zenbivy is infinitely more comfortable than any other sleep system I own.
Paired with the light 25 quilt, this is a winner of a system. Doesn't come off of the pad, the hood keeps my head warm or, when I get too warm, serves as a nice pillow and a holder for my headlamp. The comfort far exceeds any bag I've ever carried, it is truly lightweight, and packs with the quilt into a small area. Being able to sleep well is important, and this covers all the bases.
Love it! Fit my Big Agnes insulated pad just right and using another quilt I already had, it really was warm and comfortable. Now saving up to buy the matching Zenbivy quilt.
Took my new 25-degree Light Bed and sheet for a test run in the backyard. It got down to 20 degrees and I was a little cold, but added in a sea-to-summit liner and I was toasty warm again within minutes. I love that I can combine this absolutely amazingly comfortable sleep sleep system with a liner for colder nights and without a liner for warmer nights. It's light, too, and packs down SO small with the stuff sack and compression sleeves! There will be so much more room in my pack now!
