Pioneering the Future of Ultralight Insulation

In 2025, Zenbivy was the first to introduce Muscovy to the outdoor market—now, we’ve expanded that innovation even further, pioneering ExpeDRY™ Muscovy 900FP from ALLIED Feather + Down and Ultrasonic Muscovy™ 950FP+ from Softie.

We're also introducing our first-ever synthetic Ultralight Bed powered by PrimaLoft® Gold insulation. Alongside our tried-and-true ExpeDRY™ Goose 900FP, you'll have four premium insulations to choose from!

Ultra-Soft Fabrics

Zenbivy’s Ultralight Bed features premium 10D Pertex® Quantum fabrics, a feather-light, soft-to-the-touch fabric that feels like cloth—never sticky or plasticky—thanks to its unique design that doesn’t require calendering on both sides like other ultralight fabrics.

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

Block Draughts

Together, the hood and wings of the sheet create a draught shield. Attaching your quilt to the draught shield keeps it "tucked" at your sides to block draughts 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 draught 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.

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.

Fits Most Mattresses

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

Ultra-Compact

Starting at just 567g total and compressing down to the height of a Nalgene bottle, the ultra-compact Ultralight Quilt and Sheet is optimised for avid backpackers looking for comfort at the lowest possible weight and bulk.

  • 10D Pertex® Quantum

    Other backpacking quilts use thin, sticky fabrics that cling to you like plastic wrap in damp or warm conditions. To maximise comfort, Zenbivy Ultralight Quilts use premium “full-dull” Pertex® Quantum. Feather-light and soft to the touch, it's fabric that feels like fabric, not a rubbish bag.

  • 900FP Muscovy Down

    Muscovy down is a high-loft, low-cost 900FP down sourced from free-range Muscovy ducks. Its large, resilient clusters provide warmth and performance comparable to premium goose down, but at a more affordable price.

  • 900FP ExpeDRY™ Goose Down

    ExpeDRY™ is the future of performance and sustainability, using a chemical-free bonding of non-toxic gold particles to the down clusters to aid in evaporation so the down dries faster and stays dry in high humidity conditions.

  • Lightweight Clip Attachments

    Our color-coded clip system is nearly weightless compared to zippers and proven draft-free.
