It's cold outside, you're at the toll booth ready to throw change into the hopper and the struggle begins to unzip the that vinyl window. And then you have to try and zip it up while pulling out, or risk the wrath of horn-honkers behind you. Stop struggling and start using Bestop® Upper Door Sliders. You can just slide a glass panel open, do your thing and then just as quickly slide it shut. The perfect accessory for 1988-1995 Wrangler soft top owners with fabric upper doors. When the weather starts getting colder, Upper Door Sliders start flying off our shelves.
