2026 Louisville Slugger KK41 1PC Powerloaded USSSA Slowpitch Softball Bat: WBL4235010

The Louisville Slugger 2026 Genesis Kyle Knechtel (KK41) 1PC Powerload USSSA Bat is built for hitters who want that one-piece connection with a true power-loaded finish through the zone. This is a 1-piece composite designed to feel direct and aggressive—when you barrel it, the response is immediate and loud.

The bat features Louisville Slugger’s SSP-PowerTech Composite, built for a quicker break-in and strong, consistent compression as you keep swinging. Add the 1 oz Powerload end weight and you get the extra momentum that helps turn good swings into damage. The 13” barrel gives you plenty of hitting surface, while the Double-Wall Barrel System and the patented XPND End Cap are designed to optimize the sweet spot and performance toward the end of the barrel.

It’s finished with a new PVC knob designed for comfort and a lighter feel in the hands, plus the Premium LS Pro Comfort Grip for tack + cushion and consistent control. Approved for USSSA, ISA, and NSA, and backed by a 1-year limited warranty.
