Our Legendary Soft 50D Pongee Liner

Core Beds are optimized for maximum comfort at camp. Its ultra-soft 50D Pongee liner delivers the familiar feel of your favorite bed sheets—luxurious, breathable, and cozy.

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.

Fits Most Mattresses

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

25" Sheets Fit Narrower Mattresses

Using a 20" mattress? Don't worry—the 25" sheet works on it too! Simply cinch the strap and the drawstring at the bottom.

Comfort-Mapped Fabrics

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

Why Pair Your Quilt With a Sheet?

  • Woman demonstrating how the 2-piece Zenbivy sleep system blocks all drafts, unlike its competitors which lift to let in cold air as you turn over.

    Block 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.

  • Demonstration of how the 2-piece Zenbivy sleep system eliminates constriction and keeps the quilt on the mattress.

    Eliminate 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.

  • Close-up of Zenbivy sheet with integrated insulated hood in light blue and navy, designed to securely hold a mattress and keep campers warm.

    Insulate Your Head

    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.

  • Close-up view of Zenbivy sheet's built-in headboard clips securing a Zenbivy SoftTop™ Pillow in place on a camping mattress.

    Clip In Your Pillow

    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.
