Something is brewing–and it’s bad news for the other team. The Limited Edition 2026 Louisville Slugger Kryo Thundernight (-11) fastpitch bat is built for elite slap hitters and young travel ball players looking to create chaos on the basepaths. A crackling violet pattern comes to life across the GO-EX1 Barrel System–a composite gapped wall design and internal disc system that works with the XPND End Cap to deliver unmatched feel, performance and sound. Shorter lengths (28”-31”) feature a redesigned, longer barrel profile with an expanded sweet spot and lighter swing weight–empowering younger, smaller players to connect with even more pitches.
