Engineered for consistent performance, the 2023 Vapor (-10) USA Baseball Bat from Louisville Slugger showcases your raw talent when you step into the batter’s box. With an extremely stiff one-piece construction and a redesigned Series 7 Alloy Barrel crafted for a lighter swing weight, the Vapor does damage without fuss or frills. This stiff, one-piece bat pairs its alloy barrel with a new HUB 1-Shot End Cap to optimize performance and maximize durability.
