The most water-tight folding tonneau cover on the market

The UnderCover Flex Tonneau Cover is a hard-folding, extremely water-tight truck bed cover. It can be drive in 3 riding positions - fully open, 3/4 bed access and full bed access with the cover propped for maximum storage. Prop rods secure the truck bed cover so that it can be driven with it fully propped open.

The Flex panels' SLAM Latches automatically latch to the cover's mounting rails, making it extremely easy to operate from either side of your truck bed.

Water-tight seal keeps water away

The tonneau cover is fully fit with rubber seals around the perimeter of the cover to keep rain, moisture and snow from entering the cargo area.

It also features drain tubes which will carry moisture out and away from your truck bed to keep your cargo and gear dry and secure.

Quick and easy installation

The installation of the Flex Tonneau Cover is quick and easy - it features a no-drill installation. It is easy to attach or remove the bed cover without any tools needed.

The secure design uses the SLAM Latch system to secure your belongings safely in your truck bed.
