Ultra-Soft Fabrics

Zenbivy’s Ultralight Bed features premium 10D Pertex® Quantum fabrics, a feather-light, soft-to-the-touch fabric that feels like cloth—never sticky or plasticky—thanks to its unique design that doesn’t require calendering on both sides like other ultralight fabrics.

Sleep Like You Do in Your Bed at Home

A Zenbivy bed is built like your bed at home with a sheet below you and a quilt above. Our patented 2-piece design allows for the most comfortable and natural night’s sleep outdoors.

The Zenbivy Ultralight Quilt + Sheet is the only complete ultralight sleep system on the market that's draft-free, constriction-free, versatile, and warm. Other quilts and sleeping bags just can't compare.

Fits Most Mattresses

The Zenbivy Ultralight Sheet is designed to fit most standard size mattresses on the market, including rectangular and tapered styles.

Explore the Features

  • Blocks Drafts

    Together, the hood and wings of the sheet create a draft shield. Attaching your quilt to the draft shield keeps it "tucked" at your sides to block drafts and guides the corners of the quilt into the hood to seal in warmth around your neck and shoulders.

  • Eliminates Constriction

    The sides of the draft shield function as hinges, allowing the quilt to move freely, expanding and settling naturally while keeping the quilt from falling off the mattress. This unique design instantly gives you space when you need it and the ability to wrap the quilt snuggly around you when you want it.

  • Fast Footbox™

    Unlike sewn footboxes that restrict your movement and do not vent, Zenbivy’s patent-pending Fast Footbox™ uses a single clip that allows it to expand for more space or narrow for more warmth.

  • Kylie-Curve™

    Other quilts have a drawstring running the full width of the quilt. When cinched, it’ll shorten, lifting the sides and letting in drafts. The baffle-backed Kylie-curve™ cinches only the center of a Zenbivy quilt, leaving either side loose to drape around you or tuck into the hood to block drafts around your shoulders.

  • Thermally-Mapped Baffles

    We designed our quilts for thermal efficiency, distributing the down fill to provide the most warmth where it's needed, with smaller baffles to minimize downshift. We focus primarily on keeping the heat at your core and feet, but provide ample insulation in every chamber for consistent warmth.

  • Semi-Rectangular Design

    Other quilts are commonly hourglass in shape, creating a pinch point that causes the quilt to grab and twist as you move. Zenbivy quilts are semi-rectangular, providing you the space and freedom to move naturally—without constriction.

  • Integrated Insulated Hood

    Unlike a traditional backpacking quilt + straps combo, Zenbivy sheets feature an integrated hood to insulate your head. Sheets are available in insulated styles for full mummy bag warmth or uninsulated styles for use in warmer weather or to line with a down jacket.

  • Built-in Headboard Clips

    The sheet's integrated hood acts as a built-in headboard, with loops to clip in your Zenbivy SoftTop™ Pillow to keep it from sliding off the mattress.

Ultralight, Ultra-Compact

Starting at just 19.7 oz total and compressing down to the height of a Nalgene bottle, the ultra-compact Ultralight Quilt and Sheet is optimized for avid backpackers looking for comfort at the lowest possible weight and bulk.

Explore the Materials

  • 10D Pertex® Quantum

    Other backpacking quilts use thin, sticky fabrics that cling to you like plastic wrap in damp or warm conditions. To maximize comfort, Zenbivy Ultralight Quilts use premium “full-dull” Pertex® Quantum. Feather-light and soft to the touch, it's fabric that feels like fabric, not a trash bag.

  • 900FP Muscovy Down

    Muscovy down is a high-loft 900FP down sourced from free-range Muscovy ducks. Its large, resilient clusters provide warmth and performance comparable to premium goose down, but at a more affordable price.

  • 900FP ExpeDRY™ Goose Down

    ExpeDRY™ is the future of performance and sustainability, using a chemical-free bonding of non-toxic gold particles to the down clusters to aid in evaporation so the down dries faster and stays dry in high humidity conditions.

  • Lightweight Clip Attachments

    Our color-coded clip closures are nearly weightless, proven draft-free, and practically disappear when you're using the quilt on its own.
