Size Guide
The quilt is sized to fit you. The sheet is sized to fit your mattress.
-
CLIP quilts and sheets are sold separately.
Sizes can be mixed & matched to create the fit that’s right for you and your mattress. All clip quilts are compatible with all clip sheets regardless of size, style, or temperature rating.
-
ZIP quilts and sheets are sold together.
Your mattress may determine what size quilt you get. For example, if your mattress requires a 30” sheet you will need to get the XL 30” ZipBed which comes with an XL quilt.
If you are an "active" sleeper or have a "wide" sleep position, consider sizing up to accommodate your sleep style.
When in doubt, size up. Unlike mummy bags, there's no thermal disadvantage to a larger size Zenbivy because the quilt is always free to wrap snuggly around you. Bigger is always more comfortable and just as warm.
Quilt Sizing
On the chart below, locate your height and overarm measurement. To get your overarm measurement, stand with your arms hanging relaxed by your sides and loosely measure around the broadest part of your chest and arms.
Sheet Sizing
Zenbivy sheets are designed to fit most standard size mattresses on the market, both rectangular and tapered styles. Sheets fit rounded-edge mattresses up to 4” thick and 3D-style mattresses up to 3.5” thick.
Quilt Dimensions
Backpacking quilts are measured by the cut-fabric dimensions. Filled and lofted quilts will be shorter/narrower. On average:
- 25°F quilts are approximately 2” shorter in both directions, for all sizes
- 10°F quilts are approximately 4” shorter in both directions, for all sizes
Convertible quilts are 6” longer when open/flat.
Circumference
The maximum circumference around your shoulders/hips/feet for each size combination when the quilt is attached to the sheet.
Dry Sack Sizing
Both the quilt and sheet will fit in the recommended Dry Sack size and there will still be room to throw in your Zenbivy SoftTop™ Pillow or a down jacket.
You can expect your bed to compress down to about half the original size of the Dry Sack. Example: 7L compresses down to 3-4L, 10L down to 5L, etc
Description
Description
The Zenbivy Core Bed is a comfortable, versatile sleep system built for backpackers who value simplicity and soft, home-like comfort at camp. It includes the Core Quilt—our most comfortable backpacking quilt, featuring a luxuriously soft 50D Pongee lining—and a Core Sheet for a secure, draft-free setup.
Product Specs
Fast Footbox™
Unlike sewn footboxes that restrict your movement and do not vent, Zenbivy’s patent-pending Fast Footbox™ uses a single clip that allows it to expand for more space or narrow for more warmth.
-
DWR-Free Liner
All Zenbivy Pongee liners are DWR-free. This is a major step in our mission to create more natural, skin-friendly, and chemical-free outdoor gear. With our fabrics already coating-free, the only treatment we use is a PFAS-free DWR on shell fabrics.
-
Comfort-Mapped Sheet
Core Sheets are comfort-mapped with 50D Pongee to add comfort where you need it and a lightweight 20D Nylon to save weight where you don't.
Versatile Fit
Our 25" sheets work on narrower 20" mattresses, cinching in at the back. All sheets are adjustable in length with a drawstring at the foot end.
Fits Most Mattresses
Zenbivy sheets are designed to fit most standard size mattresses on the market, including rectangular and tapered styles.

50D Pongee
Our legendary 50D Pongee fabric is pure luxury. It's both durable, soft and—most importantly—has a similar feel to a sheet you would use at home, bringing a familiar kind of comfort to camp.
-
20D Nylon
20D fabrics are much softer than traditional ultralight technical fabrics while being only a fraction heavier. They’re buttery-smooth, comfortable, and durable.
-
650+ FP Down
Our premium 650+ FP down is RDS (Responsible Down Standard) compliant and provides the best bang for your buck.
-
Lightweight Clip Attachments
Our color-coded clip closures are nearly weightless, proven draft-free, and practically disappear when you're using the quilt on its own.
Shop Separates
The Core Quilt and Core Sheet can also be purchased à la carte to mix and match with other Zenbivy clip beds!
