Size Guide
Overview
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.
-
Zip quilts and sheets are sold together.
Regular, Large, and XL refer to the quilt size. 25" or 30" refers to the sheet size.
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.
Our sheets fit most standard size mattresses (rounded-edge mattresses up to 4” thick and 3D-style mattresses up to 3.5” thick.) For thicker non-Zenbivy mattresses, scroll down to view our sheet guide.
Sheet Guide for Thick 3D-Style, Non-Zenbivy Mattresses
If you have a 3D mattress that's thicker than 3.5", you may just need to size up the sheet. Below is a list of common thick 3D-style mattresses and the Zenbivy sheet size each requires, if supported.

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

Why Pair Your Quilt With a Sheet?
-

Block Drafts
Together, the hood and wings of the sheet create a draft shield. Attaching your quilt to the draft shield keeps it "tucked" at your sides to block drafts and guides the corners of the quilt into the hood to seal in warmth around your neck and shoulders.
-

Eliminate Constriction
The sides of the draft shield function as hinges, allowing the quilt to move freely, expanding and settling naturally while keeping the quilt from falling off the mattress. This unique design instantly gives you space when you need it and the ability to wrap the quilt snuggly around you when you want it.

Insulate Your Head
Unlike a traditional backpacking quilt + straps combo, Zenbivy sheets feature an integrated hood to insulate your head. Sheets are available in insulated styles for full mummy bag warmth or uninsulated styles for use in warmer weather or to line with a down jacket.
-

Clip In Your Pillow
The sheet's integrated hood acts as a built-in headboard, with loops to clip in your Zenbivy SoftTop™ Pillow to keep it from sliding off the mattress.
