The bakflip-MX4 is constructed entirely from alloy materials, including heavy-duty aluminum top panels and side rails. Unlike comparable soft-folding tonneau covers, you can't simply slice through the MX4 with a pocket knife. No matter the cargo in the bed, you can rest assured that your gear's protected by a premium bed cover from BAK industries. Not only is the MX4 durable, but it's also sleek and stylish. Unlike competitors, the bakflip-sits flush with your pickup's bed rails, disappearing into your truck's profile. And with a sleek, matte black finish on all surfaces, the bakflip-looks excellent whether open or closed. If bed access is a concern, don't sweat! When you need to utilize the entire cargo area, flip the bakflip-MX4 towards your truck's bulkhead and let the integrated prop rods support the cover.
