All-Season Warmth - Only mattresses with an R-value 5 or greater will meet the thermal performance of EN-rated sleeping bags. Most mattresses on the market today that are advertised as “3-season” do not provide the warmth required to match EN-rated bags. The Zenbivy Light Mattress has an R-value 5+ for EN-matched performance and all-season warmth: no cold spots.
Quiet Comfort - No crinkly chip bag sounds here! With 180g of fully baffled synthetic insulation, the Zenbivy Light Mattress is quiet and built for undisturbed sleep.
Fast Inflation - The included oversized dry sack is sized perfectly for the fastest inflation time and doubles as fully-welded storage to keep the mattress reliably dry on the trail.
Smart Valve - The one-way reversible valve keeps air in while inflating and allows for customizable comfort with its slow-deflation "button”. When it's time to pack up, the entire valve pops out for instant, hassle-free deflation.
Light and Soft - The soft 20d polyester taffeta shell is comfortable enough to sleep on directly while still being durable and lightweight, making it the ideal mattress for backcountry trips.
(Note that only mattresses with R-value 5 or greater will deliver full temperature rating performance from EN-rated sleeping bags)

Locate your height on the ruler below to see which size quilt and sheet/mattress we recommend for you. 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. Please note that the chart below is based on the average weight for each height. If you are an "active" or "wide" sleeper, 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 Bed because it is always free to wrap snugly around you. Bigger is always more comfortable and just as warm. Questions? We're happy to help. Send us an email with your height, weight, and general sleep style and we'll help you find the right size for you.
I really notice the R-value and had no problems with a cold bottom. I also like the vertical baffles. I have a Lawson Hammock and this helps provide a little longitudinal rigidity to the hammock which helps since I side-sleep. My spouse has a thermarest neo-air with horizontal baffles. This one weighs slightly more but packs about the same size and I think is a little sturdier. I've gone all in with the full setup - pad, sheet and quilt - and love it all.
I use this 25x77 mattress with my 25 deg sheet and quilt and love it. I am 6'2" 240lbs and sleep on my side and toss a good bit. I found this to be very comfortable and accommodating. Very warm. I found that it didn't need to be extra full to carry and disperse my weight, even when on my side.
Just used my light quilt with sheet and quilt for the first time on a early December hunting trip. 5-6 thousand feet elevation. Mid 30s at night. In a 2 person teepee tent with a wood stove. I’m 5’11 tipping. 275-280. The mattress and pillow supported me threw the whole night. I woke to a full mattress I wasn’t sleep on the ground. For a guy my size. I was pleasantly surprised. Also very excited about my investment. Can’t wait to use it again. Thank you zenbivy. Amazing product!!!!!!
Had a mummy bag until I tired this zenbivy set up. I’ll never turn back to using anything else but my zenbivy!!!!
Love the gear that I won
