If you are an "active" sleeper or have a "wide" sleep position, consider sizing up to accommodate your sleep style.When in doubt, size up. Unlike mummy bags, there's no thermal disadvantage to a larger size Zenbivy because the quilt is always free to wrap snuggly around you. Bigger is always more comfortable and just as warm.

Our 2-piece ultralight 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.
Fast Footbox™ vs. Convertible Footbox
The Fast Footbox™ is our simplest, lightest, and quickest. With a single clip and minimal fuss, it easily converts from warm “mummy mode” to spacious “wide mode”.
In addition to both mummy and wide modes, our Convertible Footbox also unclips to lay completely flat. The Convertible Footbox provides maximum versatility in warmer temperatures and when used with accessories.
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.
Light Sheet Features
By clipping the Light Quilt to the hinged “wings” of the Light Sheet, it's free to get wider where and when you need it to while preventing any possible drafts from the sides as you move. Then, just as instantly, the quilt "settles" to wrap snuggly around you.
Large Insulated Hood
Tuck in under the sheet's large hood to keep your head warm on cold nights. It's roomy and wide enough to fit the arms of stomach sleepers as well! The integrated hood doubles as a cubby to keep your camp pillow from wandering off in the middle of the night.
20D Nylon Taffeta Body
The Light Sheets are made with 20D nylon taffeta. This 20D fabric is buttery-soft and smooth against your skin. It's more comfortable than sleeping directly on the mattress and, as a bonus, it helps to keep your mattress cleaner for longer!
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!
Includes an Inflation Dry Sack for fast, breath-free manual inflation and waterproof storage.
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 weather can change here in Pa. But no matter rain or shine cold or hot I can always look forward to a great night's sleep.. nothing better than climbing into my zenbivy after a long day and listening to a good rain storm. I love it! Thanks zenbivy.
This is the most comfortable as well as compact sleep system I've ever owned. Very happy with this product. I will be using it for all my lightweight fastpacking and summer backpacking adventures for many years to come.
Love my new sleep system! Just spent 3 days on the AT. Temps got into the upper 20’s and I was toasty warm. Also love the roominess since I flip around a lot when I sleep. So glad I ditched my old mummy bag for the Zenbivy!
This is not only my first ever quilt but also my first lightweight sleep system and I was honestly incredibly skeptical at how effective it would be.
After taking this out on a couple camping trips now I am happy to say this is by far the BEST sleep system I have ever owned and will likely be the last I purchase (short of upgrading to the zero degree system). Not only does this keep you cozy and warm all night long but it totally eliminates the restrictive feeling you get while using a sleeping bag.
I am also impressed on how well this packs up into the compression sack, job well done!
Thank you for a quality product, I look forward to using it for MANY years to come.
