For any young player who’s got an old soul, we’ve got the bat for you! First introduced in 1978, the Easton B5 Pro Big Barrel Bat, also known as “Green Easton,” boasted the largest barrel on an aluminum bat ever made! It’s no wonder past greats like Bo Jackson, Tony Gwynn, Barry Larkin, John Elway, and Paul O’Neill wanted it in their hands when they stepped to the plate. Forty years later, you can have it in yours, only now with new innovations worthy of the B5 Pro Big Barrel name. Let’s find out more:
BARREL
The B5 Pro barrel is made from ATAC (Advanced Thermal Alloy Construction) Alloy. This premium construction produces a bigger sweet spot and smoother feel than any other bat of its kind. The ringless barrel design with varying wall thicknesses also provides more barrel flex for faster swing speed.
HANDLE
The extra-stiff ATAC Alloy handle transfers maximum energy into the ball for increased distance, a more professional feel and performance, while its VRS™ Handle Insert reinforces the handle to reduce vibration and create an even more solid feel.
END CAP
Easton’s Speed Cap™ provides a more flexible and responsive barrel for exceptional feel on contact. The Natural Pro Balance Swing Weight results in a balanced feel for both speed and power, making it suitable for any type of hitter. This is perfectly illustrated by the legends who swung it: Larkin, Jackson, McGwire – different types of hitters who preferred the same bat.
GRIP
B5 Pro features a premium grip, which provides the ultimate combination of cushion and tack to improve feel and control.
FINAL THOUGHTS
B5 Pro is the best feeling, sounding, and performing 1-piece aluminum BBCOR bat Easton has ever engineered. It’s a re-imagining of the most iconic bat of all time, the #1 bat in College World Series history. Remember, a simple moniker like “Green Easton” doesn’t stick unless the bat delivered in every way, shape, and form. Now it’s back to change the game forever, again.

Bringing it back! Love it.
