The 2014 Easton S3 is available in BBCOR, Big Barrel, and Youth. Both the S2 and S3 share the THT 100 Scandium Alloy barrel that offers greater durability and a traditional aluminum feel. While the S2 is a two piece bat, the S3 has a solid one piece bat constructed entirely of Scandium Alloy, offering a stiffer feel through the hitting zone.
