Footbox opens completely so the quilt can be used flat in warmer conditions.  For more warmth, it can be zipped and snugged for the warmth of a mummy bag.

With an ultralight backpacking quilt at its core, the Zenbivy Bed is the most comfortable and versatile sleeping bag ever designed.

More than the sum of its smarts.

You could say that the Zenbivy Bed is the world's first two-piece sleeping bag, but its really not a bag at all. Bags are not designed to sleep in your favorite sleep position. Bags slide off the mattress.  Bags get twisted when you roll around in them.  Bags are only one size (some are warm but small, some are big but cold).

With a Zenbivy Bed, you don't slide off the mattress.  You cover it with a soft sheet and lie on it, just like at home.  The separate quilt "floats" even when zipped in, so it won't twist around you,  pin you,  or trap you. The quilt can be "tucked in" for cold weather or "untucked" for warm. The hood gives you a snug place for your head and arms, with the quilt tucked in as snugly as you want.  All without constricting your head and neck with a bag's web of cords and toggles.

The Zenbivy Bed may look weird at first, but it quickly becomes familiar:  A mattress, covered with a sheet.  A pillow.  A blanket that can be tucked in.  Just like your bed at home.

As warm and light as a mummy bag.

Solving the "Hybrid Dilemma"

The secret to the Zenbivy Bed is it's instantly free to get wider where and when you need it to. Then just as instantly, it wraps snugly around you. All without constriction. All without the quilt falling off the mattress and losing its thermal seal.

Traditional hybrid sleeping bags pin you to the mattress and are heavy because they're oversized to allow natural movement.  Zenbivy solves those problems and is the same weight as a mummy bag.

The Quilt: the core of the Zenbivy Bed

Ultralighters have long favored quilts for their light weight, versatility and comfort. But quilts alone are not a perfect or total solution.  So ultra-lighters have adapted various methods to address a quilt's lack of head insulation and tendency to fall of the mattress.  But these "fixes" (strap systems, jacket hoods and other contraptions) usually detract significantly from a quilt's comfort benefits.

Zenbivy incorporates the quilt in a way that allows for natural sleep, while making it as thermally efficient as a mummy bag. So while quilts may have been invented for backpacking, a Zenbivy Bed makes them perfect for everything.

The 2 piece design allows the ultimate in versatility.  From car camping to backpacking, the separate quilt allows you to go anywhere in comfort.

Backcountry comfort has arrived.

Size Guide

Unlike mummy bags, there is no thermal disadvantage to a larger size Zenbivy Bed because it is always free to wrap snugly around you. So bigger is always more comfortable and just as warm.  If you are an "active" sleeper or have a "wide" sleeping position, you may want to size up to sleep naturally.  When in doubt, size up.
