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 with rounded sides, 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.
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 about half the size of its recommended Dry Sack. (Ex: 7L compresses down to 3-4L, 10L down to 5L, etc)
Introducing the Base Mattress — Reliably comfortable, warm, and durable, the Base Mattress is perfect for any car camping or backpacking trip, and is a great option if you’re upgrading from a closed cell mattress or buying your first camp pad.
The Base Mattress achieves an all-season, ultra-warm R5 with the same premium foam core found in our Flex Mattress and pairs it with a durable 75D Polyester Taffeta for a no-frills mattress that delivers. The Base Mattress is self-inflating, but for faster manual inflation you can pair it with an Inflation Dry Sack (not included). The smart reversible valve allows you to inflate it with ease, and dump air quickly when you’re ready to pack up and head home.
The Base mattress is everything you need, and nothing you don’t—a tried and true mattress that will give a good night’s sleep no matter where you are.
Inflation Dry Sack sold separately.
Warm — The foam-insulated Base Mattress is unusually warm, offering an R-value of 5 for all-season warmth and EN-matched performance.
Durable — Constructed with a sturdy 75d Polyester Taffeta for both the surface & base of the mattress to provide long-lasting durability in the outdoors.
Portable — Suitable for backpackers and car campers alike, the Base Mattresses start at 1 lb 12 oz and pack down to roughly 10" x 5" in size.
Easy Set Up — The Base Mattress's reversible valve keeps air in while inflating and out while deflating, making set up and take down easy. The Base Mattress is self-inflating, but the valve is compatible with our Inflation Dry Sack for faster manual inflation. Inflation Dry Sack sold separately.
(Note: Only mattresses with an R-value of 5 or greater will deliver full temperature rating performance from EN-rated sleeping bags)
