Our Legendary Soft 50D Pongee Liner

The Core Bed is optimised for maximum comfort at camp. Its ultra-soft 50D Pongee liner delivers the familiar feel of your favourite bed sheets—luxurious, breathable, and cosy.

All Zenbivy Pongee liners are DWR-free—a major step in our mission to create more natural, skin-friendly, and chemical-free outdoor gear. With our fabrics already coating-free, the only treatment we use is a PFAS-free DWR on shell fabrics.

Core Bed Footbox Styles

  • 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.

  • Fixed Double Footbox

    The Core Quilt Double features a wide and spacious fixed footbox that allows you to tuck in on cold nights and still be able to naturally move your feet and sprawl or quickly "kick off the covers" if needed.

Fits Most Mattresses

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

Double sheets work on one mattress, or two!

  • Comfort-Mapped Fabrics

    Core Sheets are comfort-mapped with 50D Pongee to add comfort where you need it and 20D Nylon to save weight where you don't.

  • Versatile Fit

    Our 25" sheets work on narrower 20" mattresses, cinching in to fit.

  • 50D Polyester Pongee

    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.

  • 20D Nylon Taffeta

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

  • 650FP RDS-Compliant Down

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

  • 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.
