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"

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° Synthetic 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 patent-pending 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 Zenbivy quilt cinches only the center portion. It softly seals around your neck while leaving either edge loose to drape at your sides or tuck up into the fitted sheet's hood to block drafts.
Synthetic Insulation — Our 1d/3d XD synthetic is so soft you'll swear it's down.

Without zippers or a complex convertible footbox, the Core Bed’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.
Soft, Durable Fabrics
With its legendary soft sheet-like 50d Pongee liner and a new amazingly supple and durable 30d Taffeta shell, the Core Bed features our softest fabrics yet!
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 into the sheet’s hood to block drafts.
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.
I haven’t used it yet; I’m just gearing up for a Fall section hike on the AT. Quilt definitely seems to fit the bill, but… I also ordered a mesh bag not knowing that it came in one. Also, it supposedly stuffs into the 7L bag, which I can’t make happen. Luckily, I had ordered elsewhere a 10L bag that it barely stuffs into. The compression ends I ordered? I can’t seem to make them work. Overall, I do feel I wasted some of my money.
So far, so good!
As a 6'7"/250 lbs side-sleeper, I've been camping in my 1980's era XL Hollofill 2 sleeping bag out of necessity, but it's always been snug. At various points over the years, I've tried upgrading, but everything available was too tight in the shoulders/hips, or my feet/head would get pushed together if I tried to stretch out.
Finally decided to try the Zenbivy XL Core Synthetic 25 with the 30x80 sheet paired with the ALPS Mountaineering Nimble Insulated pad.
Haven't been outside yet, but it's an absolute dream combo on the hardwood floor at my parent's house. (Curse you brother, for taking the bed! :) ) But the joke's on him, this is almost as good as a bed.
Looking forward to seeing how it performs outdoors in a couple months at the next Scout campout.
Good setup based on the fact that I've spent a number of nights sleeping in this combo and there was no glaring discomforts or things that made me regret my purchase. I'm still learning how to use the bivy and sheet combo. Overall it's good at maintaining comfortable temperature in the summer.
First time quilt. Didn't know what to expect. Wanted a 3 season 40°f synth bag, but they are out so got the 25°f. Was after I returned an excellent bag from elsewhere, ...loved it but the shoulder girth was impossible to deal with. I was a little concerned about the footbox on this one, I wanted the open bottom with zip style for controllable ventilation (I sleep hot), but this feels like it will be well workable (like when I want to hang a leg out to cool or whatever).
I am a little concerned about summer with this considering it really reflects heat surprisingly well. I figured since they didn't have the 40°f in stock, this should be fine ...considering the form factor, and also I tend to sack out mostly in the mountains and high desert ...where even in summer it tends to get colder at night anyway. We'll see ...gonna keep this one ...it is surprisingly very comfortable.
I love how I can control ventilation so well, including fully sealing up for zero draft if need be -which I had some trepidation about it actually being able to achieve. And no constriction. Wont know about the durability of its construction till its been beat up a bit, so I cannot comment on that. But I gotta say this is one of my most exciting camping gear purchases in a long time. Impressive gear.
