For all its utility, a tonneau cover is a magnet for scratches, scuffing, and damage. The same thing that protects cargo so well and makes trucks look so stylish can, with regular use, become a beaten up, dented, embarrassing eyesore. Unless, of course, hardworking men and women use a BakFlip FiberMax Tonneau Cover.

The secret to this tonneau's durability is a fiberglass reinforced polymer top layer that resists denting, scratching, and scuffing. Never again worry about your investment being damaged into obsolescence, not when this top layer works with a heavy-duty aluminum bottom layer guaranteed to maintain its structural integrity in any weather conditions and a 2 lbs. core for uniform strength. The simple-to-install BakFlip FiberMax Tonneau Cover features rubber bumpers that protect your truck bed, truck cab, and rear window from accidental damage caused by shifting cargo, and a hinge design prevents rain and snow from damaging your cargo. This tonneau can also be easily folded up into a variety of positions, and even removed entirely, depending on the size of your cargo, and everything is locked away safely when this cover is fully closed by simply locking your tailgate.

Few investments in your truck's future pay off as handsomely as the purchase of a tonneau cover. Ensure that yours survives for a long, productive life by picking up a BackFlip FiberMax Tonneau Cover. Backed by a 3-Year Warranty.

Optional Upgrade: Choose the Standard Bak FiberMax model, or maximize your truck bed's functionality by adding the optional BakBox Folding Toolbox. This truck toolbox is strong, lightweight, easy to handle, and works seamlessly with the Bak FiberMax. (BakBox not available for all vehicles.)

Came undamaged, packed in foam. Easy to install, looks good. But I have an issue when the sections fold over each, there is not enough cushion when the lids touch. I happen to have some EPDM type tape to covered these rather sharp aluminum edges of the frame. Just concerned over the life of the product. Maybe Bakflip would like to take some attention to this area and come up with a better idea. Needs a gasket for sides of tailgate, they are sending me one. No chance on testing water issues yet.

Well packaged product arrived in two boxes in great condition. Good instructions but a YouTube video made my installation easier. Glad I went with this product as opposed to similar ones on the market.

Overall was pretty easy to install. Some things that might help is break down of parts used in install ie. shims, and takes a little bit of trial fitting to get correct fit of tonnaeu cover but once it was figures out went on and holds pretty good
