Want your board to last longer? Get a bag bro.
True that a bag will not make your new board surf any better. However, keeping it in a board bag when not in use will extend the life of your board. Whether its protecting your board from a rouge rock kicking up off the highway (you've seen what it can do to your windshield), keeping the inside of your car clear from the gooey mess of melting wax, insulating your new ride from the harsh UV rays that cause de-lamination, or keeping it safe from the luggage gorillas at the airport, a board bag is anything but optional. Get a bag that's as close to the same size as your board without being too small.
