This Armor Flex cover is solid. It looks great on my F-250 and gives me full access when I need it. Install took less than an hour and it’s held up great in all weather.

I’ve had this cover on my F-350 for a few months and it’s been awesome. It’s tough, looks clean, and gives me full access to the bed. Definitely worth the investment.
