Materials & Details

  • Close-up of Zenbivy Ultralight Bed's 10D Pertex® Quantum fabric, lightweight and soft backpacking quilt material designed for breathability and comfort.

    10D Pertex® Quantum

    Other backpacking quilts use thin fabrics that cling to you like plastic wrap in damp or warm conditions. To maximize comfort, Zenbivy Ultralight Beds use premium “full-dull” 10D Pertex® Quantum. Feather-light and soft to the touch, it's fabric that feels like fabric, not a trash bag.

  • Detail of Zenbivy quilt clip system with yellow strap, securing the quilt to sheet for a draft-free, modular backpacking sleep setup.

    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.

  • Half-Length Sheet

    The Ultralight Bed features a minimal half-length sheet to cut maximum weight while still delivering the draft-free, constriction-free night of sleep you expect from Zenbivy.

  • Zenbivy sheets are designed to fit most standard size mattresses on the market, including rectangular and tapered styles.

  • Motion graphic of woman turning over in a Zenbivy bed, compared to turning over in a competitor's quilt to show draft issue with other quilts

    Draft-Free & Constriction-Free

    Other quilts are drafty. Zenbivy beds seal out cold air—keeping you warm without restricting your movement with straps.

    How It Works
  • Motion graphic comparing Zenbivy's wide footbox to competitor's narrow, restricting footbox

    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.

  • Comparison of Zenbivy sleeping bag with others on a black background

    Insulated Hood

    Other quilts leave you exposed with no hood, or force you into awkward add-ons. Zenbivy’s sheet solves this with a built-in hood that insulates your head.

  • Motion graphic of woman turning side to side in a Zenbivy quilt with the drawstring cinched by the neck, compared to turning over in a competitor's quilt with drawstring cinched, creating gaps at the sides

    Kylie-Curve™

    Most quilts use a drawstring across the full width, which causes it to draft. Zenbivy’s baffle-backed Kylie-Curve™ solves this by cinching only the center, keeping the sides free to drape naturally or tuck into the hood, sealing out drafts at your shoulders.

  • Visual line drawing to compare a wide semi-rectangular Zenbivy quilt to the narrow, restricting shape of a competitor's quilt

    Semi-Rectangular Design

    Most quilts are cut in an hourglass shape, creating a tight pinch point that twists and tugs as you shift in the night. Zenbivy quilts are semi-rectangular and will never pinch or grab, so you can move freely.

  • Comparison of Zenbivy backpacking quilt with 'Others' on a dark background

    Thermally-Mapped Baffles

    Other quilts rely on long, continuous baffles that let down shift and clump. Zenbivy quilts use smaller, segmented baffles engineered for thermal efficiency—keeping insulation evenly distributed and warmth right where you need it.

  • Person clipping a Zenbivy SoftTop Pillow into the sheet's hood

    Headboard Clips

    You wouldn’t strap your pillow to your bed at home, yet that’s often the only option in the backcountry. Zenbivy’s sheet feature built-in loops to keep your Zenbivy SoftTop™ Pillow secure without restricting how you sleep.
