Demarini CF7 Hope Fast Pitch Softball Bat (-10) (32-inch-22-oz) : The -10 Hope packs the same punch, power and balance as the -10, however with this one, youre hitting for a good cause. A portion of the proceeds goes to helping fight breast cancer via a donation to the Breast Cancer Research Foundation. With our breakthrough D-Fusion technology now expanded to this model, this bat is more impressive than ever. Our thermofused taper reduces any unwanted vibrations while simultaneously redirecting energy back into the barrel to propel the ball on impact. Translation: the science is nasty; but it looks oh so sweet.
