Is in R DNA.

Is in R DNA.



The beauty is in the barrel for the one-piece alloy Solo, built with a thinner wall design to ensure maximum pop and light swing speed.


The Solo is a rare one-piece marvel, in that its composition and vibration-dampening handle still helps reduce stings upon contact on mis-hits.


The unmatched swing speed of the Solo begins in the uniquely-deisgned end cap, which allows for weight removal in the component. The end result is a perfectly-tuned light-swinging bat and increased swing speed without sacrificing performance.


The Solo is built with the lowest MOI – measuring mass index and swing weight – of the Louisville Slugger BBCOR lineup, providing a terrific one-piece option for everyone from players entering the BBCOR game to elite players looking to get an edge at the dish with a light-swinging model.


The all-new Premium LS PRO Comfort Grip™ is designed for the perfect mix of tack and cushion.


Make it flashy. Make it bold. Make it yours. Whatever you do, make it #CustomCrafted at Choose from countless color and personalization options to build a custom Solo for just $50 more than the inline version.
