Features
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.
Comfortably Light Fabrics — 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.
The Kylie-curve™ — The Kylie-curve™ is a 3/4-length baffle-backed drawstring along the top of the quilt. The shortened drawstring length cinches only the center portion, so it softly seals around your neck but leaves the edges loose to either drape at your sides or tuck up into the sheet’s hood to block drafts.
Quality Insulation — The Ultralight Bed is filled with premium 900 fill-power ExpeDRY fluorocarbon-free water-resistant 90/10 goose down. Goose down is a premium alternative for those who are sensitive to duck down. This top-shelf 900 fill-power ExpeDRY™ goose down from ALLIED Feather + Down is simply the lightest and the best.
Thermally-mapped Baffles — We designed our quilts to maximize thermal efficiency, distributing down to provide the most warmth where it’s needed. Smaller baffles minimize down-shift, vertical baffles around the upper body prevent down from sliding, and horizontal baffles on the top of the foot box keep down from shifting with foot movement.
Roomy Integrated Hood — Built for all sleep positions, the Light Sheet features a wide rectangular hood that provides extra space and restriction-free warmth around your head and arms. The hood also acts as a cubby to keep your camp pillow from wandering away in the middle of the night!
Light & Compact — Starting under 1 kg and compressing down to about 3-4 L in size, the ultra-compact Ultralight Bed is the best choice if you're an avid backpacker looking for comfort at the lowest possible weight and bulk.
