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.

The Fast & Light Bed 10° combines our versatile, convertible, warm Light Quilt 10° with an ultralight, half-size, uninsulated sheet to create a complete Bed at the lowest possible weight and bulk. Built for performance, it's a minimalist setup with no sacrifice to comfort!
Why the Fast & Light Bed is better than a traditional backpacking quilt
Traditional quilts typically have a strap system of sorts to keep the quilt on the mattress. They're not only constricting, but also drafty, letting cold air in at the gaps between the attachment points. The Fast Sheet solves these problems.
By attaching the quilt to the hinged "wings" of the sheet, it's free to get wider where and when you need it while preventing any side drafts as you move.
Stop chasing your pillow around all night. The uninsulated single-layer hood acts as a pocket to keep your pillow securely in place.
Not to mention the sleek and simple half-size Nylon Taffeta sheet weighs in at just 3 oz! Maximum benefits at minimal weight.
Light Quilt Features
Hook & Loop Attachments
The Light Quilt uses a series of color-coded hooks and loops to form the footbox and attach the quilt to the sheet. This not only sheds the weight of heavy zippers, but gives you more versatility in how you choose to clip it!
The Light Quilt features a 3/4-length baffle-backed drawstring on the top edge. Unlike traditional backpacking quilts that have a drawstring spanning the entire width, the shortened cord length on the Zenbivy quilt cinches only the center portion, softly sealing around your neck without shortening the overall usable width of the quilt.
Smooth Fabrics & Quality Down
No thin, clingy 10d fabrics here. We found more clever ways to ditch ounces while keeping the fabric a very smooth, comfy, and durable 20d.
The Light Quilts use top-shelf 800 fill-power HyperDRY™ down, using a natural wax-based compound to make it water resistant. It is durable, fluorocarbon-free, and RDS (Responsible Down Standard) compliant.
The only lightweight all-season mattress that is quiet, easy to inflate, and WARM. The Light Mattress is built for undisturbed sleep with 180g of fully-baffled synthetic insulation. No crinkly chip bag sounds and no cold spots!
Long gone are the lightheaded days of blowing up your mattress by breath. The Light Mattress comes with a fully-welded Inflation Dry Sack allows for easy manual inflation in under a minute.
The 2-piece design of the Light Pillow is both lighter and more comfortable than other pillows on the market. Plus, the separate pillowcase is easy to wash and provides enough space to stuff extra clothing items inside to dial-in the softness and height at which you sleep best!
The Fast & Light Bed Bundle includes a Dry Sack and Compression Caps for compact, reliable, watertight compression.
The Zenbivy Dry Sacks feature fully-welded seams for a watertight seal you can trust, instant compression through its high-speed mechanical valve, and durable yet lightweight construction. Pair it with our Compression Caps to keep it fully compressed in your pack.
*Fits the quilt, sheet, and pillow. Mattress rolls and packs separately.
