Description
The Brett Brothers entered the bat business with the goal of ensuring that coaches at all levels of ballplayers 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 the game 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.

No Pop Mark Carolin Player
Pros: Pretty
Cons: It just feels weak and flat Don’t know if it requires a long break in. Right now it is a dud
Great so far! Coach Cush Coach
Pros: LLightweight, good pop, been durable!
Cons: Feels a little light for some players
broken bat Gus Meza Player
Pros: looks and feels like a solid bat
Cons: kid got up to bat first swing and the bat broke maybe it was just bad luck who knows but i cant recommend this bat to anyone
You need this bat! Aaron Player
Pros: 1)I love this bat. The build and design of it is amazing, i like the simple design, i feel that some bats are all about flashiness over performance but this bat is a perfect mix of both! the swing weight is perfect. The sounds coming off the bat is really nice. 2)I had JustBats install the Lizard Skin grip and wow! they did fantastic, i found no issues and the grip just made the bat better!
Cons: Only con is that softball season isnt all year so i cant use the bat everyday! lol
Wood, as all bats should be. David Parent
Pros: Very light for wood, great pop. Drives the ball nearly as far as a plastic bat if you know how to swing.
Cons: The gloss black gets scratched easily, but I don’t think it will affect durability.
Nice bat John Player

Cons: A

Does Exactly What We Need it For Softball Dad26 Parent
Pros: Great training/workout bat for fastpitch players Hit it nearly all weather conditions
Cons: None
Six bat review Keith Other
Pros: We purchased 6 (3 different sizes) of these bats for our co-ed adult slow pitch softball league, where everyone had to use one of the provided bats. Most players really enjoyed using them, and the sound of a wooden bat. The bat provided a good pop, and skilled players could easily put it over a 225 fence with ease. Was nice to be able to provide 3 different sized bats for the players.
Cons: 2 of the 6 bats broke by the end of the season, right at the top of the handle. Many of the inexperienced players complained about the stinging. When playing in bad weather, the bats where slippery and ended up flying everywhere. Next season we will be sure to put grips on the bats.
Good Bat Rachel Player
Pros: Good size, light weight, durable
Cons: None at this time

Cons: none
Thunder Bamboo/Maple wood bat Perfect Combination Kevin R player
Pros: Great bat... I bought this bat because I wanted a bat for myself and that I could feel comfortable with. You know these bats just fit, sure they may sting a little but with a lil love and care and some wrap the sting just falls away...and not to mention everyone loves a new bat, since they want to be the first to splinter it! These things take a beating as well as deliver good solid hits all around even off the handle..whoops... Thanks and keep up the great work fellas!
Cons: didn't buy more than one!!!!
great bat robert coach
Pros: the best bat i ever brought it has so much pop on this bat and great balance im ready to by 3 more for my 14u team
Cons: nothing bad to say please if u really want a bat that last long and has great balance and alot of pop im very happy.
Very solid bat JF player
Pros: great feel and pop. ordered weight (33/27oz & 34/28oz) was spot on for both bats. played a wood bat tournament and both bats held up great with several teammates swinging both bats (with a few miss hits) through 5 games. found myself swinging the 27oz more as it felt quicker to get around.
Cons: none.
Great Bat. Had it for a month no wear showing. Beer League Bomber player
Pros: Great pop with big sweet spot. I have never been a power hitter. Before I got this bat it was grounders or fly outs to left. Now I consistently put 2 or 3 over the fence every game. Definitely a game changer for me.
Cons: Every guy on the team wants to use it.
Great bat Kevin M player
Pros: Nice feel to the bat and has some pop to it. Just about everybody on my team uses it.
Cons: Haven't found any cons yet.
RedStone
Pros: Light weight, which helps for smaller guys on my team like. Still has good pop.
Cons: Haven't found a con yet. We actually bought a second one, just in case first one breaks.
cattman
Pros: Awsome bat solid line drives my team really like the bat so, I'll be ordering more.
Cons:
Likwid3
Pros: The look is very attractive. Didn't get to put it to the test yet, but I will post when I do. Seems like a good bat from the feel of it to the look.
Cons: A little lighter than I thought it would be, being a wooden bat.
Omar
Pros: Great pop my entire team is using it now.
Cons:
KT
Pros: Good overall bat, inexpensive in price
Cons: The ball won't go as far as a metal bat.
HI OFCR
Pros: Great bat, I purchased this bat for a cold weather bat. Decided to use it this weekend in a tourney. great bat for base hits and control. Plus the sound of a wood bat really will get peoples attention.
Cons: Non so far.
Rich
Pros: Ball comes off quick. Nice line drive bat. Weight of 28 oz. Feels great. Handle should make this bat very durable.
Cons: none.
Silver Streak
Pros: For a wood bat the ball sure takes off. Used it for 2 games so far and no complaints yet.
Cons: I swing a 28 oz composite bat so I went down an oz. to a 27 since wood usually seems heavy but this bat is very light wish I would have gone with the 28 oz. bat.
Anonymous
Pros: Great bat...lightweight and good feel to it. Shipping was extremely fast as well!
Cons:
Manfred
Pros: Great feel and balance. Great for the hitter that likes to control exactly where the ball is going. Some of the young kids on my softball team had never hit with wood. Now they have and they love the feel.
Cons:
484Dan
Pros: So far so good- has a nice sweet spot. Didn't give it 5 stars- because I only had a chance to use it a handful of times.
Cons: None so far
dtrig
Pros: light , balanced , and pop, used it for yrs b4 all these other wood companies came along
Cons:
Jeans
Pros: Great bat for the price. It gives a bit more pop than a comparably priced BWP wood bat. I can hit hard liners to the outfield consistently. It's my favorite bat to use on our slow-pitch team.
Cons: My teammates have complained of this bat stinging their hands. I only have experienced the stinging on bad swings.
King of Swing
Pros: Great pop and reinforced handle for protection against breakage. added 20+ ft to my distance.
Cons: none
Anonymous
Pros: Good weight, feels good to swing. Sleek. Teamamtes like the looks and feel.
Cons: Would like to have had a 34 in a 27 oz weight rather than the 33.
Nick at nite
Pros: Used the bats for only two games as our local season ended, but have had great results so far and our big hitters out performed our rival teams using regular wooden bats.
Cons:
Bigmike39
Pros: Great bat! The ball just jumps off of the bat. Teammates have used it and love it too. I recommend this bat.

Shaddixmj
Pros: Solid bat. Team uses it for league play & practices. We are 3-0 thus far, scoring lots of runs, big hits with it.
Cons:
Elite Power
Pros: Ball jumps off the bat. Great for hitting line drives. Surprizing power for a bat that is so light.
Cons:
Rude
Pros: Light with a lot of pop! Very sturdy, the fiberglass reinforcement has saved this bat many times when the ball hits the handle area. Huge sweat spot. The cupped end makes the weight of the bat very balanced from end to end.
Cons: None.
SAY-HEY
Pros: Great bat has lots of pop. Use it in senior league and a lot of my team use it in place of their bat. They say the power it gives almost makes other think it is a metal bat. Plan to purchase another for me the others can use my older one. I am not muscular but since using this bat I am hitting the ball as far as the big guys. Best bat I ever had. It is not the team bat.
Cons:
JBIRD
Pros: VEry easy to get the bat around. Nice finish. Nice craftsmanship with the two materials ( Maple and Bamboo )A nice bat for the price point.
Cons: It could be a little heavier.
Nic
Pros: Great bat, has plenty of pop, I now know why they call it Thunder. In our league all three homeruns have been hit with that bat. Awesome bat!!!
Cons:
phillyfan
Pros: For a wood bat the ball really takes off. I love it
Cons: None
Tannlines
Pros: Great balance. Added control, especially when hitting down the lines.
Cons:

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.
