If you are an "active" sleeper or have a "wide" sleep position, consider sizing up to accommodate your sleep style.When in doubt, size up. Unlike mummy bags, there's no thermal disadvantage to a larger size Zenbivy because the quilt is always free to wrap snuggly around you. Bigger is always more comfortable and just as warm.

Without zippers or a complex convertible footbox, the Core Bed’s simple patent-pending Fast Footbox™ technology utilizes just one hook to quickly transform the footbox from "mummy mode" for maximum warmth to “wide mode” for maximum space.
To keep things lightweight and minimal, the Core Bed uses our proven clip system to connect the backpacking quilt to the separate fitted sheet and ensure a draft-free night of sleep.
Large Insulated Hood
The sheet’s roomy integrated hood insulates your head and arms and keeps your pillow in place throughout the night. Our insulated Core Sheet uses synthetic insulation, rated to 25°F.
Soft, Durable Fabrics
With its legendary soft sheet-like 50D Pongee liner and a new amazingly supple and durable 30D Taffeta shell, the Core Bed features our softest fabrics yet!
The 3/4 length baffle-backed Kylie-curve™ drawstring comfortably seals in warmth around your shoulders but leaves the edges free to drape at your sides or tuck into the sheet’s hood to block drafts.
Reliably comfortable, warm, and durable, the Base Mattress achieves an all-season, ultra-warm R5 with the same premium foam core found in our Flex™ Mattress and pairs it with a durable 75D Polyester Taffeta for a no-frills mattress that delivers. It's perfect for any car camping or backpacking trip, and is a great option if you're upgrading from a closed-cell mattress or buying your first camp pad.
The 2-piece design of the Quilted Pillow makes it superior to other camp pillows. The separate pillowcase is easy to wash and provides enough space to stuff extra clothing items inside to dial-in the softness and height at which you sleep best!
