Something is brewing—and it’s bad news for the other team. The Limited Edition 2026 Louisville Slugger Kryo Thundernight (-10) fastpitch bat is built for elite slap hitters and young travel ball players looking to create chaos on the basepaths. A crackling violet Thundernight design comes to life across the GO-EX1 Barrel System, a composite gapped wall construction with an internal disc system that works with the XPND End Cap to deliver unmatched feel, performance, and sound.

Shorter lengths (30"–31") feature a redesigned, longer barrel profile with an expanded sweet spot and lighter swing weight, empowering younger, smaller players to connect with more pitches and drive the offense.
