I like the look of zippers better, but they're such a pain when you want to go to the drive through, or somebody wants to talk to you from outside the vehicle etc. I understand though you'd rather have zips. nothing wrong with that. ill tell you mine has bestop ones that were on it when I bought it, so I'm not sure how old they are but the zippers are wearing out pretty badly now. I have to lube them every 2 weeks or so to keep them from binding, or separating.
