The sheet is sized to fit your mattress and the quilt is sized to fit you.
Locate your height on the ruler below to see which size quilt and sheet/mattress we recommend. Ideally, you'll want to fall somewhere in the middle of the range. If you find yourself in the yellow, you'll probably want to size up for the most comfortable fit.The chart below is based on the average weight for each height. Also note that if you are an "active" or "wide" sleeper (i.e. someone that moves around a lot), you may want to consider sizing up to allow yourself more space to sleep naturally.
When in doubt, size up. Unlike mummy bags, there is no thermal disadvantage to a larger size Zenbivy because it is always free to wrap snuggly around you.Bigger is always more comfortable and just as warm.
Questions? We're happy to help. Let us know your height, weight, and general sleep style and we'll help you find the right size for you.
The sheet is sized to fit your mattress, whether it's one of ours or your current mattress. Our sheets fit both rectangular and tapered mattresses.Note on 4-inch mattresses:our sheets will fit 4-inch thick mattresses withroundedsides, but they do not work on 3D vertical side wall mattresses that are 4" or greater.
DESIGN UPDATE: We are currently in the process of transitioning our fitted sheets over to an adjustable design to accommodate different mattress lengths. These sheets will be named 20", 25", and 30".
20" sheets will fit mattresses up to 20" x 72" x 3.5" 25" sheets will fit mattresses up to 26" x 78" x 3.5" (including 25x72 mattresses!) 30" sheets will fit mattresses up to 30" x 80" x 3.5"
See measurements for max shoulder/hip/foot circumference of each size Bed, along with the dimensions of just the quilt itself.
Dry Sack Sizing
Find your Bed on the image below and match it to its recommended Dry Sack size. Don't worry, with the recommended size there will still be room to throw in your Zenbivy pillow and even a down jacket.You can expect your Bed to compress down to abouthalfthe size of its recommended Dry Sack. (Ex: 7L compresses down to 3-4L, 10L down to 5L, etc)
The Zenbivy Dry Sack features fully-welded seams, a high-speed mechanical valve, and durable yet lightweight construction. You can leave the Dry Sack compressed as-is or pair it with our Compression Caps to keep it fully compressed, maximizing precious space in your pack.
Includes Dry Sack only.Compression Caps sold separately.
7L, 10L, or 15L? See which size Dry Sack we recommend for each of our Beds under the Specs + Sizing tab above.
Fully Welded Seams — Sewn and taped seams leak and the taping degrades over time. Zenbivy Dry Sacks are fully welded for 100% dry seams that will remain watertight throughout their life.
Modular Compression — Sewn compression sacks pull on seams and compromise the dry sack's waterproof integrity. We’ve made ours compression compatible. Separate compression will never stress seams, resulting in a more reliably waterproof dry sack. Compression Caps sold separately.
High-Speed Mechanical Valve — Waterproof breathable panels not only leak, but they are SLOW. Our high-speed mechanical valve instantly dumps air while remaining watertight for quick compression you can trust.
Lightweight and Durable — Other dry sacks on the market are either light OR durable. Zenbivy Dry Sacks are both. We’ve combined 30d ripstop nylon with a burlier 75d base to give strength where it's needed.
7L Dry Sack fits all sizes of: Light Bed 25° Light Bed 40° Synthetic

You can expect your Bed (quilt + sheet) to compress down to about half the size of its recommended Dry Sack size.
Estimated Size Packed 3-4L for the 7L Beds 5L for the 10L Beds 7-8L for the 15L Beds
All-in-one sewn compression sacks pull on seams and compromise the dry sack's waterproof integrity. We’ve made ours compression compatible. Separate compression caps will never stress seams, resulting in a more reliably waterproof dry sack.
Compression Caps are optional. They keep your already-compressed Dry Sack neat and compact in your backpack.
So far I am very impressed! The sheet fits my Outdoor Vitals 25 inch wide pad perfectly. And the quilt is super roomy for someone my size. I am 5’9” 230 lbs and very broad at the shoulders. I can barely zip up Mummy bags around me and wanted to try a quilt type sleep system. I think I have finally found a system that I can sleep comfortably in. I can’t wait to try it out in the field. Thanks Zenbivi!! Aloha!
The bag works great and the valve is fantastic. I wish the shape was a little wider and shorter instead of soong and narrow.
It is a really tight roll to fit the regular zen bivy 25 with sheet all into this easily. Without tue compression caps it will want to expand long and narrow so it is less ideal in a separated sleeping bag compartment.
Excellent way to keep your sheet and quilt in a dry small package. If you use a pack liner, you could save the weight and just stuff the sheet and quilt into the bottom of your pack, but when stored in the dry sack, you can use a small pack for day hikes and have the light bundle with you as protection for any weather change. Highly recommended!
