Set the tone early with the 2026 Marucci CATX RCKLESS Junior Big Barrel (-10), a USSSA-approved bat built for young sluggers who play fast, swing hard, and bring fearless energy to the field. Crafted with FLEX Composite Barrel technology, this bat unleashes massive barrel flex and elite responsiveness, producing loud contact and serious pop that turns heads from the first swing. The junior big barrel profile maximizes surface area, helping developing players square up more pitches and build confidence at the plate.
Marucci’s one-of-a-kind OLS Connection System creates the stiffest, smoothest interface between the barrel and handle, eliminating vibration while allowing for fluid energy transfer. The PFX Composite Handle and TFX Endcap are tailored to enhance feel, whip, and forgiveness—ensuring every young hitter can swing with purpose and power. With a mid-loaded barrel, this bat strikes a perfect balance between bat speed and impact strength, offering effortless performance for rising players.
Finished with a ring-free barrel construction for consistent flex, a custom-molded hand taper, and a bold teal Soft-Touch Grip, the RCKLESS Junior Big Barrel isn’t just for show—it’s for players ready to unleash controlled chaos. Built for power, tuned for comfort, and certified for USSSA 1.15 BPF play, this is the bat for the bold.
