Regular, Large, and XL refer to the quilt size 20", 25", and 30" refer to the sheet size
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.
Hook & Loop Attachments
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!
I have a 10 degree Light Bed that I love. I picked up a 25 degree Core Quilt during the Labor Day sale and it’s awesome! Even softer than the Light Bed and will be great for warmer 3 season camping here in Texas.
I just returned from my first 2 night trip with the Core Bed and it was fantastic. It was warm out; it only got down into the mid-60's both nights. I was able to use the quilt like a regular blanket with my legs hanging out the sides and was so much more comfortable than I ever would have been in a sleeping bag in those conditions. I also appreciated how well the pillow hood held my pillow in place. One of the most frustrating things is the hood sliding off the mattress throughout the night but the sheets' hood kept the pillow exactly where it's supposed to be. I actually want to go out on more backpacking trips just to use the Zenbivy more!
