Louisville Slugger Kryo Thundernight -11 Fastpitch Softball Bat: WBL4171010
Take your game to the next level with the Kryo Thundernight -11, a bat built for hitters who demand speed, control, and explosive performance. With its advanced barrel technology and balanced design, this fastpitch bat is ready to shine in the hands of rising players.
Bat Benefits
The Louisville Slugger Kryo Thundernight -11 is a balanced fastpitch softball bat designed for players who value quick swing speeds and consistent performance. Featuring a 2 1/4-inch barrel, this bat is powered by the GO-EX1 Barrel System, a high-performance gapped wall design that uses a bullet-proof internal disc system. This innovation not only maximizes the trampoline effect but also delivers an incredible feel and a distinct sound on contact that players will recognize instantly.
The VTX Connection Piece separates the barrel and handle, allowing independent movement that reduces vibration while improving comfort and control. This technology creates a smooth, responsive swing that appeals to both contact hitters and power hitters alike. Adding to its appeal, the Kryo’s barrel design incorporates a modern lattice look—a stylish touch that matches the cutting-edge performance built into this bat.
Louisville Slugger enhances barrel performance further with the patented XPND End Cap, which establishes a pivot point that helps the barrel “float” through the zone. The result is a more responsive hitting surface with improved energy transfer and consistency on every swing. Finally, the LS Pro Comfort Grip™ adds tack and cushion to the handle, ensuring players enjoy improved comfort, control, and confidence during every at-bat.
If you’re searching for a balanced -11 fastpitch bat that delivers elite-level performance, advanced technology, and an eye-catching design, the Louisville Slugger Kryo Thundernight -11 is built to perform swing after swing.

About the Brand
In 1842, J. Frederick Hillerich emigrated with his family from Baden-Baden, Germany to the United States. Eight years before, the 1834 Book of Sports had made its debut as the nation's first publication covering baseball. But when he arrived in Baltimore, J. Frederick Hillerich would never have dreamed of the future impact his family would have on America's favorite pastime.
After a short while, the Hillerichs moved to Louisville, where J. Fred started a woodworking shop in 1856. Two of his sons, Adam and John Andrew "Bud" were born in the United States and would later join their father in his business. By 1864 "J.F. Hillerich, Job Turning" was in operation and filled orders for businesses by custom-turning everything from balusters to bedposts.
The firm thrived, and by 1875 the little woodworking shop employed about 20 people. In 1880 Bud Hillerich, who was an amateur baseball player, became an apprentice in his father's shop. Young Bud made his own baseball bats along with bats for several of his teammates.
The debate over the origins of the first bat continues to generate controversy among baseball enthusiasts, but the younger Hillerich was most certainly involved in getting his father's business involved with what would become the company's signature item. According to company legend, the first bat was turned by Bud for Pete "The Old Gladiator" Browning in 1884. Browning was a star on Louisville's professional American Association team - the Eclipse. On a spring afternoon Bud, then seventeen, witnessed Browning break his favorite bat. Bud offered to make a bat for his hero, and Browning accepted. After the young wood shop apprentice lathed a quality stick from white ash, according to the story, Browning got three hits with it in the next game.
Louisville Slugger gloves are worn by more pitchers in Major League Baseball than any other glove.
