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.

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 uncommonly supportive Ultralight Mattress features the same supportive offset air cell structure as our Flex™ Air Mattress but swaps the stretch knit top for an ultralight 20D honeycomb embossed Recycled Polyester Taffeta, bringing the weight down to start at just 482g.
Pro Tip: Our Ultralight Mattress performs best when fully inflated - so don't hold back! The more air, the more comfort and warmth. Even at max air pressure, the air cells ensure you'll feel supported yet cushioned.

-
Supportive Offset Air Cells
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.
-
Ultra-Compact
The Zenbivy Ultralight Mattress is our lightest and most packable backpacking mattress, starting at just 1 lb 1 oz and rolling down to 6.5" x 3".

-
Mylar Layers
Mylar is a popular insulation choice for ultralight camp mattresses, but unlike other ultralight mattresses that are crinkly, loud, and provide insufficient warmth, our mattress's mylar layers “float” within to quietly reflect heat and deliver R4.5+ for EN/ISO-matched performance.
-
Embossed 20D Recycled Polyester Taffeta
Our embossed 20D Recycled Polyester Taffeta is laminated, not coated, making it stronger and more durable than other ultralight mattress fabrics.
