Fabrics & Fills

  • Close-up of soft, blue 50D Polyester Pongee fabric used in Zenbivy sleeping bags, highlighting its smooth, luxurious texture designed for camping comfort.

    50D Pongee Liner

    Our legendary 50D Pongee fabric is pure luxury. It's both durable, soft and—most importantly—has a similar feel to a sheet you would use at home, bringing a familiar kind of comfort to camp.

  • Close-up of Zenbivy Nylon Taffeta shell fabric, available in 15D and 20D, smooth and durable material used in camping quilts and sleeping bags.

    20D Nylon Shell

    20D fabrics are much softer than traditional ultralight technical fabrics while being only a fraction heavier. They’re buttery-smooth, comfortable, and durable.

  • Close-up of premium down insulation fibers used in Zenbivy sleeping bags and quilts, providing lightweight warmth for backpacking.

    650+ FP Down

    Our premium 650+ FP down is RDS (Responsible Down Standard) compliant and provides the best bang for your buck.

  • Close-up of Zenbivy's synthetic hood insulation, highlighting the soft, down-like polyester blend used for budget-friendly comfort.

    Synthetic

    Built for warmer nights, tighter budgets, and personal preferences, we’ve used a polyester synthetic blend that’s as soft as it gets. So soft in fact you’ll swear it’s down!

Core Bed Details

  • Lightweight Clip Attachments

    Core Beds feature our color-coded clip closures. They're nearly weightless, proven draft-free, and practically disappear when you're using the quilt on its own.

  • Zippers

    Core ZipBeds use zippers to attach the quilt to the sheet. Zippers are convenient, familiar, and fast! They don't take much explaining.

  • Full-Length Sheet

    All Core Beds feature a full-length sheet for full mattress coverage and maximum comfort at camp.

  • Two Black/Burgundy Zenbivy sheets on mattresses, one rectangular mattress and one tapered mattress to show versatile fit.

    Adjustable Fit

    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

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

  • 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.

  • 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.

  • 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.

  • 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 features built-in loops to keep your Zenbivy SoftTop™ Pillow secure without restricting how you sleep.
