The OT™ Iron shaft doesn’t use traditional prepreg sheet, but instead uses a new material for the golf shaft industry called Tow Prepreg. Tow Prepreg uses carbon fibers that are arranged in super-strong “bundles” (the way a steel cable is made). These bundles are impregnated with resin to create the Tow Prepreg, and then woven together like a braid.

The “braiding” technology using Tow Prepreg is incredibly resistant to twisting and ovaling and creates a shaft with no spine, so the shaft performs more consistently than a shaft made with traditional sheet prepreg. The braiding also minimizes vibration, to provide the better feedback that’s so important for iron play.
