The Flex™ Air Mattress feature an exclusive 4-way stretch fabric top that forms instantly to your shape and movement, both minimizing weight transfer and relieving pressure points.

Rolling down to just 16 x 8 cm, the Zenbivy Flex™ Air Mattress is ultra-compact and hardly take up any space in your pack.

Zenbivy’s lightest and most packable backpacking mattress. The Ultralight Mattress is uncommonly supportive and delivers R5 warmth.

The Zenbivy Ultralight Mattress is our lightest and most packable backpacking mattress, starting at just 482 g and rolling down to 16 x 8 cm.

180 g 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. 

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

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.

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.

Why is a 3D mattress superior? The completely flat top and vertical side walls make the Flex™ 3D Mattress feel like a real mattress. The top is usable from edge to edge and it cradles you like your mattress at home.

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