Comfort Plus™ InsulatedWhen we set out to design a mat that was better than what was already available, we ultimately went back to why we carry a sleeping mat into the wild in the first place to give us a better nights sleep. Better is of course a very subjective ambition and while we could have made the lightest, or the most compact mat ever designed, were stoked to present what we consider to be the most comfortable sleeping mattresses available. Happy sleeping! Air
