    The most comfortable camp mattress ever designed.

    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 camp mattresses - even at firm air pressures. Our slow-deflation valve feature allows for customizable comfort. Simply lay on the mattress and push the "button" to slowly deflate to the desired firmness until it feels as close as possible to your bed at home. Horizontally cored foam eliminates the cold spots found on most vertically cored mattresses and delivers a full R-value 5 for EN-matched performance.

    Long gone are the lightheaded days of blowing up your mattress by breath. The Flex Mattress includes our Inflation Dry Sack for easy inflation in under a minute. Simply snap the Inflation Dry Sack onto the mattress valve and push the air through.

    Exclusive 4-way stretch top

    All other camp mattresses use tightly woven fabrics that do not stretch. These surfaces transfer weight across the mattress and can feel both stiff and "bouncy". Our Flex™ mattresses feature an exclusive 4-way stretch fabric that forms instantly to your shape and movement, both minimizing weight transfer and relleving pressure points.

    Reversible high-speed valve

    The reversible valve keeps the air in while inflating and its slow-deflation "button" lets you dial in your exact comfort level. When it's time to pack up, the entire valve pops out for fast, hassle-free deflation. Snap it back in in "deflate" mode and the air stays out as you continue to roll.

    Included Inflation Dry Sack

    While the Flex™ Mattress will mostly self-inflate once you pop the valve open, it's helpful to have an Inflation Dry Sack to top it off to your desire comfort level. The Flex™ Mattress comes with a fully-welded Inflation Dry Sack for waterproof storage and easy manual inflation.
