The Marucci Bat Company uses top grade Maple billets cut from selected, naturally grown trees in Pennsylvania forests. This selection process insures the highest possible grade of wood for each bat. The Marucci Bat Company™ bats are 100 percent handmade or turned in small batches from an original design, then finished and detailed by hand. Each model is made to exacting specifications maximizing balance and ease of handling. The Marucci Bat Company™ uses an Ultra Penetrating Stain that provides the best possible finish for your next Marucci Bat. Most impressive is the Bone Rubbing technique that The Marucci Bat Company™ uses. `Boning` bats began in the earliest days of baseball with players like Babe Ruth and Lou Gehrig. These Hall-of-Famers would spend hours in their dugouts rubbing their bats with old cow femur bones. Bone Rubbing closes the wood`s pores, compressing it and making it harder. Marucci uses the same technique on their bats, rubbing before the finish is applied to seal and harden the wood. The Bringer of Rain maple wood bat is named for MLB Star Josh Donaldson and is built for colossal power. The large barrel and thick handle produce an end-loaded feel and allow for the extreme bat whip power hitters love.
