Description
2021 Easton B5 Pro Big Barrel Adult BBCOR
Baseball Bat BB21B5
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. AGAIN.

Bat Size Guide-Help Selecting Baseball and Fastpitch Bat Size
Selecting The Appropriate Bat Weight
- The bat size that best fits you will be one that is comfortable, easy to swing and allows you to produce the greatest bat speed and power.
- To obtain your optimum bat select a bat that is not too long/heavy or too short/light.
- A bat too short won't provide maximum power or barrel length, while a bat too long will be too difficult to handle and will also slow bat speed reducing power.
- First begin with selecting a length. If possible use the previous bat you swung to help establish a length. For example if you used a 30 in bat and now feel that you are ready to move on to a larger bat a 31 in could be the next step.
- You can also use the chart below for the average bat lengths based on your height, weight and age.
- The chart below is just a guide as each player's strength and bat speed differ.
- While the chart below was primarily designed for baseball, we have found it works fairly well for fastpitch bat sizing too. For fastpitch, however, refer to only the player height and disregard the player weight. Also, see notes at the bottom for additional notes on fastpitch bat sizing.

Selecting The Appropriate Bat Weight
- The bat weight is equally as important as the length in selecting the optimum bat size.
- Bat weight differs greatly depending on the age range and is usually referred to as the "drop" when associated with the length and weight.
- The drop is the difference between the length of the bat and the weight of the bat. For example if a bat is 30 in. long and weighs 20 oz. then the drop is 10. The larger the drop, the lighter the bat.
- The average bat drop can best be broken down by age range.
- Average - drop 12
- Power Hitter - drop 10
- For ages 12 and under, drop 10 is the average
- Over age 12 range from -10oz to -5oz depending on the players strength and bat speed.
- *Check with your local league or organization to find out if there are any restrictions on barrel diameter or bat weight.
- All high school or college bats are drop 3
- Freshmen/Sophmore High School players: 31 and 32 ich are the most popular
- Junior/Senior in High School players: 32 and 33 inch are the most popular
- College Players: 33 is the most popular size.
- Age 13 and under, average drop - 11oz or 12oz.
- Age 14 to 16, drop 10
- Age 16 and up, Drop 8oz to 10oz. Drop 10 is still the most popular drop, but some power hitters prefer a drop 9.
