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. Also note that 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.
You don't have to choose between an ultralight pack or comfort at camp—the Light Bed gives you the best of both worlds. Our 2-piece sleeping bag combines the warmth and draft-free performance of a mummy bag with the luxurious comfort of a backpacking quilt. It's built to feel like your bed at home with a sheet below you and a quilt above so you can get a comfortable, natural night's sleep outdoors without the constriction of a mummy bag.
We've refined every aspect to save weight including using performance fabrics, high-quality insulation, and a unique ultra-secure hook and loop system to add versatility to the setup. We built the Light Bed for performance so you can go further outdoors in comfort.
The Light Bed 40° has a 1d/3d polyester synthetic blend insulation that’s so soft you'll swear it's down. It’s just as light and packable as our 25° down quilt, but built for warmer nights and tighter budgets.
The Light Bed 40° Synthetic includes the Light Quilt 40°, Light Sheet 40°, and an extra-large mesh bag for long-term storage. (Mattress, pillow, and compression sold separately)
Zipper-less Configuration — Sure, we were able to shed weight by going completely zipper-less, but that wasn’t the only perk. By equipping the Light Bed with a system of color-coded hooks & loops, you can attach the quilt to the sheet in multiple different “modes”, giving you even more versatility in how you choose to use it.
Comfortably Light Fabrics — You'll find that most backpacking quilt makers shed weight by using thin, clingy 10d fabrics. We found more clever ways to ditch ounces while keeping the fabric a very smooth, comfy, and durable 20d. 20d fabrics are much softer than traditional ultralight tech fabrics while being only a fraction heavier. Definitely worth it!
The Kylie-curve™ — The Kylie-curve™ is a 3/4-length baffle-backed drawstring along the top of the quilt. The shortened drawstring length cinches only the center portion, so it softly seals around your neck but leaves the edges loose to either drape at your sides or tuck up into the sheet’s hood to block drafts.
Quality Insulation — Built for warmer nights and tighter budgets, we've used a 1d/3d polyester synthetic blend that is as soft as it gets. It's the next best thing to down!
Roomy Integrated Hood — Built for all sleep positions, the Light Sheet features a wide rectangular hood that provides extra space and restriction-free warmth around your head and arms. The hood also acts as a cubby to keep your camp pillow from wandering away in the middle of the night!
Light & Compact — Starting at just 2 lbs and compressing down to about 3-4L in size, the Light Bed 40° Synthetic is the best choice if you're an avid backpacker looking for a comfortable warmer-weather bag at the lowest possible weight and bulk.

I am both a fidgety sleeper and usually sleep on my side with my arm under my pillow. The Zenbivy sheet lets me put my arm under my pillow while the hood keeps everything in place. If it's not cold I can put the hood over my plasticy inflatable camp pillow as a makeshift pillowcase to give it a a little floof and nicer feel. Literally the sheet alone is worth the weight to me. I love the hood without having to use a constricting mummy bag.
The clips are brilliant too though. I usually sleep with one side clipped and only clip it all up if it's cold. Either way is perfect for all the tossing and turning I'm gonna do. After a night or two I was able to do all the clipping in the dark while in bed, although you definitely need to figure out how it works at home. Maybe an underrated benefit, sleeping on the sheet just feels a little nicer than sleeping directly a pad.
I'm in the southern US and a hot sleeper. Summer nights are mild so the weather here doesn't push it and I can't fairly rate warmth. If I purchased again, I would've gone with the 25 degree quilt just to save a bit of weight and get a bit more versatility. I went with the cheaper one out of skepticism because I don't hear tons of serious backpackers or fancy influencers talk about Zenbivy, but it would've been worth the price. I'm 5'11" with the regular size quilt which is certainly big enough.
The only downside is that it's almost certainly a few ounces heavier than whatever other ultralight quilt you're looking at so you won't be able to flex how hardcore and barebones you are with this in your Lighterpack, as if that matters. Unless you're camping under a 3oz DCF tarp, you've sacrificed weight for comfort at some point and this is where I personally did. I would cut my shelter or food weight every time before you see me without my 9oz comfy hooded sheet thing. Now that I know how great the system is, if ZB ever wants to make a fancy 950 fill power quilt to entice me to upgrade, I'm here for it.
