So I recently purchased a Tourmaster Coaster 2 Leather jacket. I love it! The leather is real thick and the fit is perfect. The only problem ( which is kinda a BIG problem ) is the zipper. Once in awhile I will sip it up and the middle section splits open. I am very careful zipping and un zipping. I returned the first one and got a replacment, but the second one does the same thing. It uses a plastic zipper, and I am wondering if anyone else has had these problems with plastic zippers? Are metal really more reliable?
