"Carry all your gear with the extra-large waterproof cargo carrier bag from Apex. Suitable for use with clothes, hunting and fishing gear, and even snowboards. This bag can be mounted on top of your vehicle with a roof rack or built-in crossbars or use it along with large 60"" wide hitch mounted cargo carriers. The cargo bag is made from waterproof extra heavy-duty PVC coated nylon so it will withstand all the elements. The heavy-duty zipper is also enclosed with a special flap for extra protection. The six included tie-down straps allow the cargo bag to be securely attached to your vehicle or carrier."
