A Valve That Works With You.

The Zenbivy Mattresses have a unique valve that keeps the air in as you inflate and allows for customizable comfort with its slow-deflation "button" feature. When it's time to pack up, the entire valve pops out completely for fast, hassle-free deflation then flip the valve, snap it back in, and the air stays out as you continue to roll!

Flex™ Mattress — Insulation

Horizontally cored foam eliminates the cold spots found on most vertically cored mattresses and delivers a full R-value of 5 for EN-matched performance.

Flex™ Mattress — Exterior

Our 4-way stretch fabric allows this mattress to “flex” with your shape and movement, so the top feels softer and more supportive than other mattresses, even at firm air pressures.

Light Mattress — Insulation

180g of fully-baffled insulation is considered excessive when compared to most air mattresses but actually it's the minimum required to achieve R-value 5+, allowing you to get full EN rated performance from your sleeping bag

Light Mattress — Exterior

With a shell made of 20d polyester taffeta and 180g of fully-baffled insulation inside, you can say goodbye to the “space blanket crinkle” synonymous with most ultralight air mattresses.
