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 Light Quilt 10° with our Fast Sheet to give you a complete Bed at the lowest possible weight. It's a minimalist setup with no sacrifice to comfort!
What is a Fast Sheet? We would never make you use a constricting quilt strap system... Straps not only pin you to your mattress but they end up leaving drafty gaps between the attachment points. This half-size sheet with an uninsulated hood weighs in at just 3 oz but packs a punch by protecting you from drafts, keeping both you and your quilt on the mattress, holding your pillow in place, and adding comfort to your mattress with its smooth 20d Nylon Taffeta. The Fast Sheet features the same hinged "wing" design as our other sheets, so you can move around easily—without constriction and without fear of drafts.
Includes the Light Quilt 10°, Fast Sheet, and an extra-large mesh bag for long-term storage. (Mattress, pillow, and compression sold separately)
Zipper-less Configuration —The Fast & Light Bed is equipped with a series of color-coded hooks & loops to save weight and add versatility.
Light & Compact — Starting at just 2 lb 4 oz and compressing down to about 5L in size, the ultra-compact Fast & Light Bed 10° is the best choice if you're an ultralight backpacker looking for comfort and warmth at the lowest possible weight and bulk.
Comfortably Light Fabrics — You'll find that most down 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 — The Light Quilt is filled with premium 800 fill-power HyperDRY™ down. This down uses a natural wax-based compound to make it water resistant. It is durable, fluorocarbon-free, and RDS (Responsible Down Standard) compliant.
Thermally Mapped Baffles — We designed our quilts to maximize thermal efficiency, distributing down to provide the most warmth where it’s needed. Smaller baffles minimize down-shift, vertical baffles around the upper body prevent down from sliding, and horizontal baffles on the top of the foot box keep down from shifting with foot movement.
Integrated Hood — The Fast Sheet features an integrated, un-insulated hood that acts as a cubby to keep your camp pillow from wandering away in the middle of the night.

Sizing Help Quilts are available in Regular, Large, or XL Fast Sheets are available in 20x72 (for 20" mattresses) or 25x77 (for 25" mattresses) Please match the sheet size to the width of the mattress you plan to use it on. See our Size Guide for more information.
Flat Quilt Dimensions* Regular: 78” x 54” (198 x 137cm) Large: 86” x 58” (218 x 147cm) XL: 90” x 64” (229 x 163cm) *Please note that the listed quilt dimensions are for the cut fabric. Filled, lofted quilts will be several inches smaller in both length and width.
Recommended Dry Sack Size The 10L Dry Sack will fit all sizes of the Fast & Light Bed 10°. You can expect your quilt and sheet to compress down to about half the size, or 5L. Dry Sacks are sold separately.
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.
Fast Sheet Features
Keep It Draft-free
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.
The sleek and simple half-size Nylon Taffeta sheet weighs in at just 3 oz! Maximum benefits at minimal weight. *Mattress sold separately.
The uninsulated hood acts as a pocket to keep your pillow securely in place. On cold nights, tucking the quilt up into the hood will help prevent drafts. *Pillow sold separately.
Already have a mattress you love? Our Fast Sheets will fit both rectangular and tapered style mattresses. The sheets are available in 20" and 25" widths. There are a set of adjustable straps on the back to cinch it in and keep it securely in place.
