The storm grows stronger with the 2026 Louisville Slugger Kryo Thundernight (-9), a limited-edition fastpitch bat engineered for elite players who demand both power and precision. This model takes the already dominant Kryo platform and fine-tunes it for stronger hitters who thrive with more mass behind their swing.
Its bold violet crackle design showcases the GO-EX1 Barrel System, a gapped-wall composite with an internal disc system that creates explosive sound, unmatched feel, and reliable performance across the entire hitting surface. The XPND End Cap works seamlessly with the barrel to optimize flex and energy transfer, ensuring maximum responsiveness on every swing.
The -9 drop weight provides a heavier swing feel compared to the -10 and -11 models, making it the perfect fit for experienced high school and college-level athletes in the middle of the order who want extra power without losing control. The Kryo Thundernight (-9) balances pop, comfort, and consistency—helping hitters attack the ball with confidence and authority.
