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.

So far the cover is very nice; the seals on the sides & ends can be made of a little thicker rubber.

Undercover Flex, excellent

Just installed the Undercover Flex on my new 2015 F-150 Platinum and it looks great. Truck has not been in a down pour yet, but stayed dry through three days of light rain. Easy to fold up and really simple to install...accomplished in 30 minutes by myself. AutoAnything was a pleasure to do business with.

Good cover, Poor attention to detail

Cover was very easy to install. 30 min. Works well. The only water issue is around the tail gate. Very small amount. Shipping was fast and product was protected well during shipping. Issues, seal around edge cut poorly works but looks bad. Sticky substance on top of one of the panels will not come off. Strut bracket screw holes not lined up on the rails. Looks like someone did not care what they shipped out.

Great product at a good price!

This Undercover Flex was very easy to install. Having never installed one before, it took me 15 minutes. Had to adjust it once in that time so it was squared. It isn't completely water tight as some complain about, but it keeps the rain out as it should. Don't store fine art canvases under it and you'll be fine. I love it, the look, the ease of access (yes, you have to close your tailgate before you close it as others have also complained about, that's how it's secure, duh!). 5 Stars!
