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.

Received my cover a few months ago and so far, so good. The experience with Auto Anything was great and the shipping was fast! So far, the cover seems to be holding up well, will actually take it for its first road trip this weekend, but don't foresee any issues.

It's okay but not as good as bak tonneau cover I brought for my Titan. It's not as flush as I would like. I will continue to make adjustments to get a good snug fit. The drain tubes are very hard and no good if the bed has the sprayed in liner. It doesn't feel as heavy as I would like. It's good for keeping things safe and out of sight.

Great cover

Bought this for a 2014 ford raptor. Install is very easy. A helping hand is recommended. Have a hard time getting it completely perfect and centered. Always seem to have the latches more on one side. One panel might be perfect and the other not. Could be that I have a bed liner. So far no leaks in the rain. Would really recommend the cover. Quality is great.

The rubber was separated on top of the cover, and come apart were it was stick up and leak, use super glue. Hope it works. Thanks

The cover is easy to install with good instructions. It had a small amount of water after installing but after a week of sitting in the sun the seals have settled in place. I have taken it through several automatic car washes since with no leaks
