Carbon & Kevlar // Tail Patches - Can usually be found glassed into the tails of most of our shortboards stocked at the shop, used to help prevent excessive denting or crushing of the tail. Carbon Strip -  Is placed on the bottom of some stock boards, running from the tip of the nose down the center of the board. Strategically placed the carbon stiffens up the flex-pattern and gives the board more drive by creating a ridged flex pattern, that allows the flex to load up and release, springing you into the next section or turn with all the speed/drive you need.
