【Montbell】 U.L. Comfort System Pad 1400 x 500 Junk Item The surface isn't very dirty as it hasn't been used much, but air leaks from the sealed areas, possibly due to aging. Air leaks even when inflated through the valve, so please understand that this is a junk item before purchasing. The pad repair kit is unused, so if you are able to repair it yourself, would you be interested?
