Arriving in March!

Built for Convenience in the Backcountry

The Core ZipBed is our most comfortable and convenient bed—built for backpackers who want the ease of zippers and maximum comfort at camp.

Zip It!

The Core ZipBed delivers the draft-free, constriction-free comfort Zenbivy is known for, with the added ease and familiarity of zippers.

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.

Legendary Soft Pongee Liner

The Core ZipBed's ultra-soft 50D Pongee liner delivers the familiar feel of your favorite sheets from home—in the backcountry!

  • DWR-Free Liner

    All Zenbivy Pongee liners are DWR-free. This is 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.

  • Comfort-Mapped Sheet

    The Core ZipBed'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.

  • Versatile Fit

    Our 25" sheets work on narrower 20" mattresses, cinching in at the back. All sheets are adjustable in length with a drawstring at the foot end.

Fits Most Mattresses

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

Explore the Materials

  • 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 Down

    Insulated with 650FP down, it delivers loft and warmth without any additives for a more natural—and more affordable—sleep system.

  • 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.
