Whether you are spending the night out, or waiting to take a shot on a deer the Ambush mattress won't let you down. Built on the same premise as their Toughskin sleeping pads the Ambush has been built with both closed cell and open cell foam. The closed cell foam is on the underside of the pad making the pad resistant to punctures.
This product has been marked as irregular; there may be blemishs, but the function of the pad has not been compromised.
