BAKFlip F1 Cover is the most “Advanced Tonneau Cover Ever Made!” The BAKFlip F1 operates exactly the same as the BAKFlip G2, however the outer paneled surfaces are made out of FRP (Fiberglass Reinforced Polymer) which provides unparalleled impact resistance while the aluminum surfaces underside the cover ensures absolute structural integrity! The BAKFlip F1 also has a higher density EPS core than the G2, has superior impact resistance, stays cool to the touch with some refinements in the operating components and their fit and finish under the cover. The cover looks very similar (if not almost identical) to the G2, but the difference is the FRP on the outer panels. These outer panels come in a UV protected black finish, they stay cool to the touch, and provide superior performance in extreme weather and a 2 year factory warranty!
