When the CAT 5 burst onto the baseball scene, it became one of the top aluminum bats on the market. This year, Marucci raises the stakes again with unbelievable new technology in the CAT 6. Through endless field testing with the top players in America, Marucci discovered that vibration in the top hand is the most common complaint amongst amateur baseball players. Marucci has acquired a patented new anti-vibration technology that blows the competition away. They hired noted bat scientist Dr. Daniel A. Russell to do some lab testing against the top bats on the market. The results were shocking. He found that the vibration dampening rate on the CAT 6 is 5.6 times higher than the next closest competitor! For the player, this means that they can step up to the plate worry-free with one thing on their mind; blasting one over the fence! This is literally the smoothest swinging bat ever produced.
