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.

- 30” sheets fit mattresses up to 4.5” thick (4" thick if 3D sidewalls)

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

The Sweet Spot of Ultralight Performance and Value
The UL Dirtbed™ delivers ultralight performance without the premium ultralight price tag. By balancing weight savings with value-driven materials, it offers the best bang for your buck in the ultralight category.
Starting at just 3 ounces, the uninsulated Fast Sheet is the lightest way to block all drafts and eliminate all constriction.
-
Ultralight & Uncommonly Supportive
The offset air cells create a diagonal baffle pattern that causes the mattress to twist against your body’s natural fold lines rather than collapse into them like horizontal and vertical baffles, resulting in a more supportive mattress.
-
Minimalist Pillow
The 2-piece Minimalist Pillow includes a removable pillowcase and an adjustable air bladder, letting you customize both height and firmness. Layer your down jacket or other soft clothing on top of the air bladder for ultralight comfort!
*Down jacket not included
-
Fully-Welded, Waterproof Storage
The Zenbivy Dry Sacks feature fully welded seams for a long-lasting watertight seal, a high-speed mechanical valve for instant compression, and durable yet lightweight construction. In other words: it's the best dry sack on the market.
- 7L for UL Dirtbed™ 25°F
- 10L for UL Dirtbed™ 10°F
