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)
The versatile, minimalist design of a backpacking quilt makes it an ideal choice for anyone wanting to reduce the weight and bulk of their sleep system. The zipperless Zenbivy Light Quilt is lightweight and compact but prioritizes both comfort and adaptability. Between our super soft 20d fabric, convertible draft-free zipper-less foot box, carefully engineered baffle system, and pure semi-rectangular shape, we’re certain our Light Quilt is not only the most versatile quilt on the market but the most comfortable as well. Premium 800 fill-power HyperDRY™ down rounds out the package and delivers a final quilt that is weight competitive with much more expensive offerings while delivering on Zenbivy’s promise of maximum comfort.
The Light Quilt 10° is WARM. It’s built for colder sleepers and those pushing the boundaries of “3-season”. Add a Light Sheet 10° to create a complete Bed that allows you to fully clip in when temperatures drop.
Includes the Light Quilt and a large mesh bag for long-term storage. Sheet, mattress, and accessories sold separately.
Zipperless Versatility — Our Light Quilts are offered in two styles: Fast Footbox™ or Convertible Footbox. The Fast Footbox™ is our simplest, lightest, and quickest. With a single clip and minimal fuss, it easily converts from warm “mummy mode” to spacious “wide mode”. In addition to both mummy and wide modes, our Convertible Footbox also unclips to lay completely flat. The Convertible Footbox provides maximum versatility in warmer temperatures and when used with accessories.
The Kylie-curve™ — The Kylie-curve™ is a 3/4-length baffle-backed drawstring on the top edge of our quilts. Unlike traditional backpacking quilts that have a drawstring spanning the entire width, the shortened cord length on the Light Quilt cinches only the center portion, so it softly seals around your neck but doesn't shorten the overall usable width of the quilt. By cinching only the center, either edge of the quilt is left loose to drape at your sides to block drafts as you move and turn over.
Thermally Mapped Baffles — We designed 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.
Purely Semi-Rectangular – The Light Quilt is purely semi-rectangular. This not only provides full coverage when used flat but 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.
Quality Materials — The Light Quilts are filled with premium 800 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 Fabric — Most ultralight quilt makers shed weight by making their fabric a thin and clingy 10d. We opted to find clever ways to ditch ounces while keeping the fabric a very soft, comfy, and durable 20d. 20d fabrics are much softer than traditional ultralight technical fabrics while only being a fraction heavier.

It was a restful warm November 11-12, 2022, at 10,000 feet at about 30 degrees on top of Mount Lemon in the Meadow inside my Light Quilt 10 degree. This will be a great Arizona backpack quilt for me.
This was by far the best money I've ever spent on a sleep system. If you are worried about staying warm, you wanna keep your sleep system lighter and compact, AND you're mummy sleeping bag makes you shiver with a mild case of claustrophobia... get a Zenbivy. It was light, packed down small, super easy to set up and was comfortable to sleep in. The worst thing I'll say is that I took the 10 degree light quilt on a fall packing trip and sweated my *ss off... so I'm heading back to pick up the lighter quilt for the warmer season.
I love this quilt! The material is fantastic, it’s light weight, and I love how I can use it so many different ways.
While no one would actually mistake me for a princess, I am one when it comes to my sleep system. I need it lightweight, warm, smooth and roomy or I will toss and turn while awake all night. This system exceeded my expectations. It is versatile, packable and beyond comfortable. I can kick my feet every which way and not wake up. I seriously have not had this great of sleep in the backcountry—maybe ever. I definitely recommend this to the picky sleeper.
I used this and the corresponding mattress for 6 nights recently with some nighttime temperatures dropping to -5C. Very warm, comfortable and quiet. The ability to sleep on my side or stomach without getting wrapped like a burrito or feeling constricted was a revelation. System was also somewhat lighter than my old Big Agnes mattress and similarly temperature rated MEC mummy bag.
