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.

First off, I had a Retrax on my 2005 DC Tundra. It rattled so much I could never put the rear window down. Also I had to remove it when I need the full capacity of my truck bed. I researched the Flex and Bakflip Fibermax for my new 2014 DC Tundra. All the reviews sounded pretty even. Since AutoAnyhting sells both, I decided to call them for their input. The sales guy I talked with recommended the Flex over the Bakflip, so that is what I bought. I'm VERY happy with this decision. I love it..

Good product

Love the cover. Easy to install, it took me about a half hour by myself. Only issue is the rubber seal freezing to the tailgate in the winter.

Installed the cover in about 30-45minutes. Installing the rails would be much easier with a second person, but it can be done by one. I am please with the look, functionality and sturdiness of the cover. Unfortunately during the first rain I noticed that one of the seems were leaking. I contacted UnderCover and the warranty covered the product defect. I am receiving a new replacement cover. Overall I love the cover and have received many compliments on it. Overall GREAT costumer service.
