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 Core Quilt is Zenbivy's simplest, softest, and most affordable backpacking quilt. Without zippers or a complex convertible footbox, the Core Quilt's simple patent-pending Fast Footbox™ utilizes just one hook to quickly transform the footbox from "mummy mode" for maximum warmth to “wide mode” for maximum space. The soft 50d Pongee liner and supple new 30d Taffeta shell provide maximum home-like comfort in the backcountry.
Includes the Core Quilt 25° and a large mesh bag for long-term storage. Mattress and accessories sold separately.
Fast Footbox™ — Without zippers or a complex convertible footbox, the Core Quilt's simple patent-pending Fast Footbox™ technology utilizes just one hook to quickly transform the footbox from "mummy mode" for maximum warmth to “wide mode” for maximum space.
Clip Closures — To keep things lightweight and minimal, the Core Quilt uses our proven clip system to connect the backpacking quilt to a separate fitted Core Sheet and ensure a draft-free night of sleep. Core Sheet sold separately.
Soft, Durable Fabrics — To maximize comfort, the Core Quilt features our legendary soft sheet-like 50d Pongee liner and a new amazingly supple and durable 30d Taffeta shell.
The Kylie-curve™ — The 3/4 length baffle-backed Kylie-curve™ drawstring comfortably seals in warmth around your shoulders but leaves the edges free to drape at your sides or tuck around you to block drafts.
Thermally Mapped Baffles — We designed our quilts to maximize thermal efficiency, distributing down to provide warmth where it’s needed most. 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.
RDS Compliant Down — The Core Quilts are filled with premium 650 fill-power down from Allied. This down is RDS (Responsible Down Standard) compliant.

Pairing your Core Quilt with one of our Core Sheets allows you to fully "tuck in" when temperatures drop. Hooking the quilt to the fitted sheet protects against drafts and keeps you (and your quilt) on the mattress. Plus, the hood acts as a cubby to keep your pillow in place all night long.
Our soft Pongee Core Sheets are available with an insulated hood for full "mummy bag" warmth, or with a lighter-weight uninsulated hood for use in warmer weather or paired with an insulated hooded jacket.
