    Block Drafts | Zenbivy Sleeping Bag Systems

    Block drafts

    Together, the hood and wings of thesheet 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.

    Eliminates Constriction | Zenbivy Sleeping Bag Systems

    Eliminates 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.

    Fast Footbox  Zenbivy Sleeping Bag Systems

    Fast Footbox™

    The Fast Footbox™ is our simplest, lightest, and quickest. With a single clip and minimal fuss, it easily converts from warm “mummy mode” to spacious “wide mode”.

    Kylie Curve | Zenbivy Sleeping Bag Systems

    The Kylie-curve™

    The Ultralight Quilt features a 3/4-length baffle-backed drawstring on the top edge. Unlike traditional backpacking quilts that have a drawstring spanning the entire width, the shortened cord length on the Zenbivy quilt cinches only the center portion, softly sealing around your neck without shortening the overall usable width of the quilt.

    Semi-rectangular design

    Other quilts are commonly hourglass in shape,creating a pinch point that causes the quilt to graband twist as you move. Zenbivy quilts are semi-rectangular, providing you the space and freedom tomove naturally-without constriction.

    Thermaly mapped duffle | Zenbivy Sleeping Bag Systems

    Thermally-mapped baffles

    We designed our quilts for thermal efficiency, distributing the down fill to provide the most warmthwhere it's needed, with smaller baffles to minimize downshift. We focus primarily on keeping the heat at your core and feet, but provide ample insulation in every chamber for consistent warmth.

    Integrated Insulated Hoody | Zenbivy Sleeping Bag Systems

    Integrated Hood

    Zenbivy sheets feature an integrated hood to insulate your head. Sheets are available in insulated styles for full mummy bag warmth or ininsulated styles for use in warmer weather or to line with a down jacket.

    Headboard Clips | Zenbivy Sleeping Bag Systems

    Built-in headboard clips

    The sheet's integrated hood features built-in headboard clips that attach to your Zenbivy pillow to keep it from sliding off the mattress, just like your headboard at home.

    *Only new 2024 sheets and pillows feature the clip attachments. 2023 and older models do not.
