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.

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.

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.

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.

    10D Pertex® Quantum

    Other backpacking quilts use thin, sticky fabrics that cling to you like plastic wrap in damp or warm conditions. To maximize 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 trash bag.
