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

Shed Some Light on Your Gear
The transparent panel isn’t just for looks—it’s a built-in light source. Unlike fully-opaque dry sacks, when the Ditty Dry Sack is open, the window lets light in, naturally illuminating the interior so you can spot what you’re looking for.
What Fits in Each Size?
-
2L
Perfect for your smallest essentials. Ideal for things like your phone, chapstick, headphones, etc—the daily-use items you want to keep dry and easy to grab throughout the day.
15cm x 11cm x 7.5cm rolled or 25cm unrolled
-
3L
The ideal size for most backpackers. Great for organising all your trail staples like a toothbrush, headlamp, phone, etc. Small enough to tuck away, big enough to carry what matters.
23cm x 11cm x 10cm rolled or 28cm unrolled
-
5L
Made for bulkier items. Store larger electronics (like battery packs), first aid kits, binoculars, etc. Great when you need a bit more space without losing organization.
25cm x 16.5cm x 10cm rolled or 28cm unrolled

Smarter Shape, Easier Access
Unlike narrow, tube-shaped dry sacks that quickly turn into a bottomless pit of smalls, the Ditty Dry Sack is designed with a wider, shallower shape—so your stuff spreads out, not up.
-
Instant Compression
The Ditty Dry Sack’s high-speed, one-way mechanical valve instantly releases excess air—so you can compress it down to save pack space, without compromising waterproof protection.
-
Lightweight, Durable Construction
We’ve combined a lightweight yet durable 30D ripstop polyester body with a burlier 75D polyester base to give extra strength where it's needed.
-
Fully Welded, Watertight Seams
Sewn and taped seams leak and the taping degrades over time. Zenbivy Ditty Dry Sacks are fully welded for 100% dry seams that will remain watertight throughout their life.
