Since 1884, Louisville Slugger has been on the cutting edge of bat technology. This year the TPX line brings a new dimension in performance technology to the table. The EXOGRID 2 is one of the most innovative bats to ever hit the market. This bat starts out with Louisville Slugger's SC21 Scandium Alloy which is one of the most durable and responsive alloys on the market. Moving toward the handle you'll find that the metal is trimmed into a grid-like pattern and replaced with carbon composite inserts. These inserts are several times stronger than the metal they replace which gives the EXOGRID 2 not only its name, but it's unwavering durability. Inside the bat, the heart of the EXOGRID 2 can be found in the form of an internal carbon composite sleeve. This provides greater handle stiffness than alloy alone ever could. All of these parts are brought together using Louisville Slugger's EXOGRID Bi/Fusion Process, where a combination of heat and extreme pressure bond everything into a single, solid unit. New for the BBCOR model this year is Power Disc Technology. Two independent discs are positioned inside the barrel to allow for peak performance around the sweetspot, and providing an oversized hitting surface and balanced swing weight. Not only will you get a higher performing swing with the EXOGRID 2, you'll get a better feeling one! Louisville Slugger: Intimidate at the Plate! The EXOGRID 2 is BBCOR certified and legal for high school and collegiate play. It carries a Full Twelve (12) Month Manufacturer's Warranty. Free Shipping!
