Zenbivy Core Bed

Unlike restrictive mummy bags, the Core Bed uses a semi-rectangular shape that mimics a standard bed. It pairs a quilt with a fitted sheet, allowing you to move naturally and sleep in any position without feeling trapped.

The Core Bed is rated for 10 degrees Fahrenheit, which is suitable for winter conditions. However, if you are sleeping in temperatures significantly lower than that, you will likely need to supplement with additional base layers or a warmer sleeping pad to maintain comfort.

Yes, the integrated hood is designed to stay stationary while you move. It also includes a specific attachment point to keep your pillow secure throughout the night, preventing it from sliding away.

The footbox features an adjustable design that allows you to cinch it tight for maximum warmth on colder nights or expand it for extra room and ventilation when temperatures rise. This flexibility makes it a versatile choice for varying conditions.

The system is designed to work best with standard rectangular sleeping pads. Because the fitted sheet relies on a secure fit to seal out drafts, it may not function as intended on unusually shaped or extremely thick pads.

By combining down and synthetic insulation, the system leverages the high warmth-to-weight ratio of down while utilizing synthetic fibers in areas prone to moisture or compression. This provides a reliable, durable sleep environment that performs well in diverse backcountry conditions.
