THE GREEN EASTON IS BACK! First introduced in 1978, the original B5 Pro Big Barrel bat boasted the largest barrel aluminum bat ever made to that point in time for a larger sweet spot. And after 40 years in the making, all of Easton’s innovations have produced a new breakthrough worthy of the B5 Pro Big Barrel name. The new B5 Pro features a ringless barrel with varying wall thicknesses. This premium Advanced Thermal Alloy Construction (ATAC) produces a bigger sweet spot and smoother feel for B5 Pro than any other bat of its kind. And, combining its construction with Easton’s Speed Cap, the B5 Pro also provides a more flexible and responsive barrel. Additionally, the bat’s Natural Pro Balance Swing Weight results in a balanced feel for both speed and power. Its Extra-Stiff ATAC Alloy Handle transfers maximum energy into the ball for a more professional feel and performance, while its VRS Handle Insert reinforces the handle to reduce vibration and create an even more solid feel. The B5 Pro also has a premium grip, which provides the ultimate combination of cushion and tack. Not only is the 2021 B5 Pro the best performance, feel and sound that Easton has ever engineered in a 1-piece aluminum BBCOR bat, the bat’s design is a modern remix of The Green Easton’s classic look. THIS CHANGES EVERYTHING.
