When it comes to gymnastics, politics and truck bed cargo control-flexibility is key. And, there's no better way to touch your cargo-covering toes than with the Undercover Flex Tonneau Cover. Undercover's first folding tonneau features a sleek, low-profile design that folds away to reveal your entire truck bed.

Featuring 3 folding panels, the Flex cover folds completely forward and back to deliver full bed access and maximum security. The low-profile design sits flush with your truck's bedrails for a super sleek and slippery style that improves MPG, too. And, thanks to the simple clamp system, the Undercover Flex is easy to install and remove with no drilling required.

Crafted from a fiberglass reinforced polymer with a subtle textured finish, the Flex shoulders up to 400 lbs. And, it'll never crack, warp, fade, rust or corrode. Connected by seamless leak-proof rubber seals and featuring an integrated drain tube, the entire assembly keeps your bed clean, dry and secure. Best yet, Undercover backs your Flex Tonneau Cover with a 3-year warranty.

This bed cover is very easy to install. I really like knowing that whatever I put in the bed of my truck is safe from criminals and weather. I love the low profile look of this cover.

Great look and function!
