Flex™ Air Mattress

$127.49 ~~$209~~ In stock

The Flex™ Air Mattress is theonly ultralight air mattress to feature a 4-way stretch top. In combination with the supportive offset air cell structure, there's truly a "wow" moment when you lay on it. Starting at 1 lb 4 oz, delivering EN/ISO-matched warmth, and packing down to just 6.5 x 3 inches, the Flex™ Air Mattress is ultralight backpacking luxury.

Pro Tip: Inflate firmer than you're used to. The Flex™ Air gets its softness from the air cells and stretch fabric, not from under-inflating, so run it harder than a traditional pad even if you like it softer.

After years of camping on hard ground, the offset air cell structure on this mattress finally gave me a full night's sleep without waking up sore. It's surprisingly stable too, I barely noticed my partner moving around.

I've had cheap air mattresses before that felt like sleeping on a pool toy, but this one actually cradles you. The offset cells keep my hips from bottoming out when I sleep on my side, and the stretch top somehow makes it feel less like plastic. Used it three nights camping and woke up without the u

That first moment lying down really is a "wow" — the 4-way stretch top cradles you while the offset air cells support without any sagging. Hard to believe something this ultralight can feel so solid. I'm genuinely impressed.
