The next level up from classic cover offering a little more protection for your board over the most basic board bag. Good all around protection for your board and one of the best investments to protect your car or van from wax and sand. Dings of course are often prevented going into and out of the house where most of them happen! Of course if you are traveling or hanging out on the beach then the board bag literally saves your board from being "Sun" burned or delaminating if in the back of your truck or on top of your car. This one is the 3 d fit for one board so less flappy material to deal with and a vent strip helps the inside stay cooler in theory!
