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.
Includes the Flex™ Mattress, Inflation Dry Sack, and repair kit
The Flex™ Mattress
Horizontally-cored Foam
Horizontally-cored foam cuts weight and eliminates the cold spots found on most vertically-cored mattresses and delivers a full R-value of 5 for EN-matched performance.
Supportive 4-way Stretch
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.
Reversible 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.

Tyler K.
United StatesLoses air from bad seals
It’s either bad seals or this thing is absolutely not meant to be rolled tight or stored for a long period of time. There is no noticeable puncture hole - and cannot hear a leak. But I’ll inflate to max capacity and within 5 minutes at room temperate it’s deflated down to 75% its original capacity. In cold weather it’s worse. Agreed with the commenter below.

United StatesGood
I was fortunate enough to be gifted this. The mat is simple in construction, but sturdy. I was surprised at how stiff I was able to make the bag, and it held up well to a full night's sleep without any leaking. A little bulky, but quality.
