Quick Overview


The whole reason why drive our trucks in the first place is because we like options. Fortunately, that’s where the Undercover Flex Tonneau Cover excels. It’s not only sleek and sturdy, but it folds back to allow full bed access faster than you could say, "How do I get off this balance beam?"
When it comes to having an efficient hauling setup, innovation is always welcome. Featuring three folding panels. Undercover backs your Flex Tonneau Cover with a solid 3-year warranty.
