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.

Our Legendary Pongee Liner, Now DWR-Free

In 2025, 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 PFOS-free DWR on shell fabrics.

  • Comfort-Mapped Sheet

    The ZipBed Trek's sheet is comfort-mapped with 50D Pongee to add comfort where you need it and 20D Nylon to save weight where you don't.

  • Simplified Sizing

    We made the choice to discontinue our 20" sheet. Our 25" sheets work on narrower mattresses and we find that most people are using a mattress 25" or wider. More space, more comfort!

Fits Most Mattresses

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

How our patented 2-piece design works to...

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.

& 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.

  • 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.

  • 700FP HyperDRY™ Down

    Built for performance, our premium 700 fill-power HyperDRY™ down from ALLIED Feather + Down uses a natural wax-based compound to make it water-resistant. It is durable, fluorocarbon-free, and RDS (Responsible Down Standard) compliant.

  • Zippers are perfect for someone looking for convenience in situations, such as car camping, where weight doesn’t matter quite as much.

    Zipper Closures

    Zippers—you know 'em, you love 'em, and they don't take much explaining. While they may be heavier than clips, they're familiar & fast, making them a great option for someone wanting maximum convenience.
