Stephen H.wrote a review of Big Agnes Air Core Ultra Sleeping Pad on July 17, 2017
Familiarity: I've used it several times
Every big agnes pad I've ever owned has had leaked after only a few months of use. I imagine the leak was somewhere in the valve. These pads also take a dizzy amount of energy to fill. No doubt comfortable but no way to repair the leak in the valve without sending it back. Big Agnes has always been really helpful with exchanges and warranty issues but even the pads that got swapped out had the same problem. Four pads between the q core and air core series.
