The Zenbivy system is more comfortable than a sleeping bag, that's for sure! But it is not perfect... After seven nights of use, a seam near an attachment between the quilt and the sheet broke, letting down escape, with my confidence in the quality of the seams in the same time. Also I find that the hood is too small if you use - like me - a pillow : it's ok for the pillow, it's ok for my head, but tight for both. I still recommend zenbivy system, but there are improvements to be made...
The hood is designed for both a head and a pillow. The 20" wide sheet you have has less room, obviously, than the 25", which would be the size we would recommend for most men. If the hood it too tight we would recommend the next size up, realizing that has significant ramifications due the the change in mattress size. We have a 3-sigma QA protocol and measured defect rate of less than .5%. Any defects are covered by lifetime warranty.
I came across Zenbivy when looking for a bag which would secure to the sleeping mat and use the mat for the ground side insulation to minimise pack bulk, and eliminate sliding off the mat in the night. I'd had one of these years ago but it was a closed foot mummy style so also wanted one which had more freedom to regulate temperature, and could also be unzipped for use as a quilt. I bought the Zenbivy Bed and Pillow eight months ago, have used them regularly over that time on overnight and multiday sea kayaking adventures, and found the bed to be simple and nice to sleep in, and the pillow to be comfy and quiet, preferring it to be only around half inflated. The sheet attaches easily to the mat and the hood is great for when it gets cold, and to hold the pillow in place. Winter came along and I needed a warmer bed so bought a Zenbivy Lite 10 and a Flex self inflating mattress. Again, after a little self tuition and practice using the online videos and guides, found it simple to use, and toasty warm at -1 C inside a silk liner with bare feet and foot box domed but open. The Lite lofts up wonderfully and Flex is importantly quiet and warm to sleep on, self inflates well, and the reversible valve is smart and excellent for when rolling up again. The flexibility of multiple sleeping configurations to suit different applications is an absolute bonus. Well done Zenbivy on excellent concept, design, execution, quality, and customer service.

Unlike mummy bags, there is no thermal disadvantage to a larger size Zenbivy Bed because it is always free to wrap snugly around you. So bigger is always more comfortable and just as warm. If you are an "active" sleeper or have a "wide" sleeping position, you may want to size up to sleep naturally. When in doubt, size up.
