I really like the overall quality of the Port Authority vests; I purchased two.  We were snowbirds in Arizona when purchased so I didn't wear them much until we returned to Montana a couple of week ago.  They have not even been washed. The second time I had worn this navy one I noticed after zipping it half way up that the bottom of the zipper had separated, the part that I already zipped up. It is now past Amazons return date.  So Im hoping if Port Authority reads this they will make it right.
