My Aero Highwayman is only about 4 years old. Yesterday, after getting up from sitting I noticed that the jacket had unzipped from the bottom. So I forced the pull down to open it up and rezipped it. It took only a tiny bit of tugging on the bottom two sides to separate it again and again. I noticed that the zipper backing on the male side had started to pull away and fray. I assume this is what's causing the separation. I'm a little upset at how quickly this happened but that's life. Guess I'll contact Aero and ship it off to them for replacement. Might as well also have them replace the liner as it has a few holes in it already from my stupidity. I just hope they can reuse most of the needle holes and my jacket doesn't return looking like it was attacked by a child with a stapler. : ) Any comments, suggestions? Thanks for listening to my tale of woe.
