Zenbivy Sleep System Sizing Guide
On the chart below, locate your height and overarm measurement. To get your overarm measurement, stand with your hands by your sides and measure around the broadest part of your chest and arms.
Regular, Large, and XL refer to the quilt size
20", 25", and 30" refer 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.
Circumference
The maximum circumference around your shoulders/hips/feet for each size combination when the quilt is attached to the sheet. Regular, Large, and XL are quilt sizes. 20", 25", 30" are sheet/mattresses sizes.

Dry Sack Sizing
Find your bed in the image below and match it to its recommended Dry Sack size. Both the quilt and sheet will fit and there will still be room to throw in your Zenbivy pillow!
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
