Pioneering the Next Era of Down Innovation

NEW! ExpeDRY™ Muscovy

As pioneers in down innovation, Zenbivy is proud to lead the way again, being the first to bring ExpeDRY™ Muscovy to the outdoor market.

Feather-Light, 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.

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.

Explore the Materials

  • 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.

  • Lightweight Clip Attachments

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

  • Ultrasonic Muscovy™

    The pinnacle of natural performance, Ultrasonic Muscovy™ delivers uncompromised loft, durability, and stability. Washed using a patented Ultrasonic Washing process, it exceeds industry standards of cleanliness and preserves the down’s pure, additive-free loft for long-term performance.

  • ExpeDRY™ Goose
