The Best Overall Tri-Fold Tonneau Cover
The UnderCover Flex Tonneau Cover is our top pick as the best overall tri-fold tonneau cover from UnderCover.

The cover has a low-profile design and seamlessly integrates with the truck bed for a flush, OEM factory finish look. Weather-resistant seals prevent moisture from seeping into the truck bed. Integrated drain tubes further enhance weather protection by channeling water away from the cover.
Convenient and Secure
The UnderCover Flex can be positioned in different configurations based on access needs. You can keep it completely folded open, partially folded with the first panel open, or fully closed and flat. The cover stays securely in place in each position using dual latching handles on the sides.
When completely closed, the tailgate lock feature provides peace of mind by preventing unauthorized access to the truck bed. The cover cannot be opened when the tailgate is locked.
Easy No-Drill Installation
The UnderCover Flex can be installed in less than 30 minutes without any drilling using a clamp-on rail system. The clamps slide inside the truck bed rails and tighten for a secure grip. Removal is just as easy by simply loosening the clamps.
Pre-set adjustment points on the rails allow the cover to fit snugly on most truck beds from the factory without the need for adjustments.
