The before and after photos tell the story: Project TJ Reboot’s original upper door halves were trashed. The material was faded, worn, and torn; the zippers were broken, stuck, or missing; and the vinyl windows were so sun damaged, scratched, and opaque that you could barely see out of them. The new Bestop Upper Door Slider’s fabric is crisp and clean, and there are no zippers to hassle with. The real glass window slides open and can be easily kept clean. Best of all they pop in and out of the metal lower door halves just as quickly and easily as the old uppers. Now, we can actually see what’s next to us on the road or trail, without taking the upper door halves off.
