Only got to use once

Had to exchange first coat as the arms ran small for coat size.Second coat (larger size) fit good and was happy at first. Exactly what I wanted.I work outdoors and got to use the coat in the rain once. Coat was in good shape when I put it up to dry. A few days later I got it out of my truck to use and the plastic was cracked/torn everywhere. Like it was dry rotted or something. (see photo of blue coat above) I would send back but it cost me $9 to send the first one back. So I would have more invested in postage than the coat is worth. First thing I ordered on-line that I am unhappy with.Very disappointed.
