Description
The Brett Brothers entered the bat business with the goal of ensuring that coaches at all levels of softball have access to superior quality composite wood bats that are cost effective. Consistency and durability were the primary factors when establishing their bat designs. The Brett Brothers have been involved in ball their entire lives, through Bobby and John's Minor League careers to the Professional careers of Ken and George. The Brett Brothers know the game. Even today it's an important part of their lives, with each brother being involved in their own way. George, who is still a part of the Kansas City Royals Organization and a hometown hero here in Kansas City, was a career .305 hitter with 3 Batting Titles, a 1985 World Series Ring and an induction to the Hall of Fame in 1999 to round out his 21 year career in Kansas City. Not only did he prove to be a consistent hitter he showed that he had the knowledge to succeed. The Brett Brothers understood that having reliable wood was an important component. This is why they implemented their 3-piece laminating system along with their patented BOA reinforcement handle. The all new Thunder model is uniquely designed with a bamboo core and a maple barrel.

Great wood softball bat David Bressler Player
Pros: Great balanced feel and decent pop for a wood bat. Durable and looks good as well.
Cons: None
Great bat, nice feel Javier Player
Pros: Light and feels really good when making contact with ball.

1 1 player
Pros: It’s got some pop and I’m getting some hits too
Cons: na
What I was looking for! Gary player
Pros: Good sweet spot (easy to find) Lighter weight Good solid hits
Cons: Can't think of any
Brett Thunder SST500 Black/Red Charlie "PLAY BALL" gABBEART other
Pros: First time using by multiple players, so far everyone is impressed with it ( ours being a wood bat league only ). Durability is still to be determined.
Cons: NO CONS AT THIS TIME
Doug Doug player
Pros: Great feel. Great weight and pop action
Cons: Durability. Seems like we need to get a new one every other season
love the bat Tom M. player
Pros: great weight and balance i've used it in one game so far and it felt like i've been using it forever many others on the team loved it as well
Cons: no cons for me
This Thunder was a dud, sorry!! D player
Pros: none
Cons: Bat was not very good, hit like a fungo bat, needed more bamboo or maple or something on the sweet spot. Seemed to not be able to get a good hit off it. Maybe it was a so called lemon that creeps in to some of the ones that are made. Thanks for trying.
Best deal around jake player
Pros: Perfectly balanced, great pop, good torque on your swing for a wood bat. This bat actually feels more comfortable in my hands than most aluminum bats that I use.
Cons: none
wood bat cody player
Pros: all around good bat
Cons: none
Great bat for me Matt player
Pros: Solid construction, ball flies off the barrel. I am no home run hitter, I just put the ball in play and this bad helps make that happen. I am hitting great line drives and can really place the ball well to all fields with substantial power. I prefer a little bit of a heavier bat, it helps keep me from trying to more than I can, so this is perfect for me.
Cons: None
not what i expected Michael player
Pros: none yet
Cons: barrel too small.
League president and player Phil other

Cons: None

Frank
Pros: Solid bat...nice pop...one of the first bats picked up by our players....
Cons:
Say-Hey
Pros: The bat has excellent pop. I have been hitting the ball with more power and as far as some of the best hitters in the league. It must be the bat because I haven't developed bigger muscles.
Cons: Only bought one and my team players are all using it.
cokie
Pros: great balanced bat you can thunder the softball
Cons: none

About the Brand

The Brett Brothers “entered the bat business with the goal of ensuring that coaches at all levels of baseball have access to superior quality composite wood bats that are cost effective." The Brett Brothers have been involved in baseball their entire lives. We are four brothers and all of us played professional ball at one time. Bobby and John played in the Minor Leagues, and Ken and George together put in 31 years in the Major Leagues.
Not only did we play baseball because we were good, we truly loved the game. Even today we closely follow the sport. George still works for the Kansas City Royals. Ken has been a broadcaster for 11 years with Fox. Bobby runs our professional franchises here in Spokane, the baseball Indians and the hockey Chiefs. The oldest brother John is a frequent visitor here to see his brothers and watch our teams play.
Like most baseball families, it all started in a small Southern California town call El Segundo. The boys are all about two years apart, and we had some kind of sporting event about every night. I remember most of our family meals were hot dogs, and everything was on the fly. Our parents were always there to cheer for us, and our lives were generally very happy.
Ken was the first to sign a pro contract at age 17. He was the fourth player taken in the annual draft by the Boston Red Sox. When their scout Joe Stephenson came to sign him, our dad said, "the one you really want is the skinny, barefooted one, George." George in 1966 was all of 12 years old.
If you move up the clock to 1971, George was a senior, and Joe Stephenson desperately wanted him to be Boston's #1 pick. The Red Sox said no, and the Kansas City Royals took George in round #2. The rest is history. Ken played 11 years for numerous teams. George turned out to be exactly the player our late father envisioned. He was a 3-time winner of the Batting Title in three different decades. He was very consistent, and always played the game very hard. He was the greatest Royal, and still makes his home in Kansas City. In the summer of 1999, he was awarded Baseball's highest award, election to the Hall Of Fame in Cooperstown, New York.
In the spring of 1998, the Tridiamond Bat Company needed a place to "try out" their new baseball bats. Because the Bretts owned the only local professional team, an association was formed. When Tridiamond got both NCAA and Major League approval to sell bats, they needed some baseball help. At this time we bought into the company and changed the name to Brett Bats.
