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.

The Fast & Light Bed 40° Synthetic combines our convertible Light Quilt 40° Synthetic 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. The Fast Sheet is a half-length sheet with an uninsulated hood starting at just 3 oz but it packs a punch by protecting you from drafts, housing your pillow, keeping your quilt from sliding off you, 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 40° Synthetic, Fast Sheet, and an extra-large mesh bag for long-term storage. (Mattress, pillow, and dry sack 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. The quilt's convertible footbox provides maximum versatility in warmer temperatures.
Light & Compact — Starting at just 1 lb 10 oz and compressing down to about 3-4L in size, the ultra-compact Fast & Light Bed 40° Synthetic is the best choice if you're an ultralight backpacker looking for comfort and performance 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 either edge loose to 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!
Integrated Hood — The Fast Sheet features an integrated, uninsulated hood. On cold nights, you can tuck the corners of the quilt up into the hood to block drafts around your neck and shoulders. The hood also acts as a cubby to keep your camp pillow from wandering away in the middle of the night.

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 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 either edge loose to drape at your sides or tuck up into the sheet’s hood to block drafts.

On cold nights, tuck the quilt corners up into the hood to block drafts around your neck and shoulders. The uninsulated, integrated hood also acts as a cubby to house your camp pillow.
