The most essential part of any camping equipment is your sleep system. Your whole game is thrown off if you’re not well rested. I used to sing the praises of the Teton Sports ComfortLite. Now that I’ve upgraded my tent to a 2013 Subaru Outback, the ComfortLites just aren’t cutting it. I decided to go all out and invested in the Exped MegaMat Duo 10 as my car camping mattress of choice.
