Sleeping bags are great for camping and backpacking, but there's a reason we don't sleep in them at home every night — they're far more restrictive and stifling than a loose quilt. Mummy bags are especially tight-fitting, while rectangular bags offer more room. Last year, Zenbivy developed a system that blends the features of a quilt, rectangular bag, and mummy bag into one modular sleep system.

Based on feedback from the original Zenbivy, the company has created a second model that offers reduced weight and a zipperless design. The new Zenbivy Light Bed recently launched via a crowdfunding campaign on IndieGoGo. It will be available in either a 10°F or 25°F temperature rating, each filled with 800 fill power HyperDRY water-resistant duck down.

Like the original, the Zenbivy Light Bed is designed to be used in tandem with an air mattress. The lower layer of the Zenbivy system attaches to the mattress, providing a hood and under-body sheet, while the upper quilt layer attaches to the lower layer with hook-and-loop fasteners. This allows the Zenbivy Light Bed to be used as a flat standalone quilt, a wide rectangular bag, or a sealed mummy bag.

To see how it works, check out the video below:

The Light Bed is available in Regular, Large, or Extra Large for either 20×72 or 25×77 mattress sizes. Weight ranges from 1lb 13oz to 2lbs 12oz; MSRP ranges from $359 to $469. “Early Bird Special” prices of about 20% off are available for a limited time via IndieGoGo.
