Quick Take
You'll need to find a 13.5 ounce T-Ball bat if you want the lightest. But, beware, its seriously light.
We can’t help but notice how perfectly adorable this tiny baseball equipment is. Easton has made a t-ball bat that is 24 inches long and, get ready for this, a DROP 13.5! The bat weighs 10.5 ounces. The Easton Ghost X 24/10.5 tee ball bat is the lightest tee ball bat on the market today.
How Light is 10.5 Ounces
294 paper weighs 10.5 ounces.
For those having trouble getting a feel for how light 10.5 ounces is, let me try to help paint a better picture. When our son JUST turned 3, the 24/10.5 ounces Tee-Ball Bat was too light for him.
Here is a video of him hitting an older version in a 24/11.
Age Recommendations for the Lightest T-Ball Bat
Our size chart doesn’t even go this low. We recommend that a 4-year-old use a 12-ounce bat.
But as their parent, you’ll know where it fits best for them. If they are small for their age or you are looking to get a bat for a 3-year-old, then this 10.5-ounce bat will work well.
Note, too, that a light bat might be the answer for any kid who is really struggling to hit the ball, regardless of age.

Ghost X Tee Ball Bat Construction
The Easton Ghost X Tee Ball bat is a single-piece aluminum bat with a 2 1/4 barrel. It has a nice, cushioned grip. It is perfect for the very small player who needs as much help moving the bat as anyone.

It is not, however, inexpensive. Most parents will balk at the $40+ price point, and we agree. At this age, paying more than $20 or so on a bat seems ridiculous. But to each his own. And if you need a 10.5-ounce bat, then you have virtually no other options.
Unless…

We also really like the HERO tee ball bat from Axe Bats. The oval knob gives kids a more natural feel. Although only a drop 11, the 24-inch is a real light swing. In part because of the oval knob that helps swing mechanics (We discuss that more here).
Lightest Tee Ball Bat Durability
Your number one concern about the lightest tee ball bat should be durability.
If you use the bat for tee ball only, with kids who should actually be swinging a 10.5-ounce bat (which are really small kids), then you will have no problem with durability.
On the other hand, if you use the bat for kid pitch or with bigger kids who swing harder, you can fully expect the bat to dent.
Light Tee Ball Bat Recommendations
We would recommend this bat for hitters who Are very tiny, want a cool-looking bat like their older brother or sister, want a bat that can be used in both serious and pretend games, and want to increase their level of adorableness.
We would not recommend this bat for hitters who weigh more than 40 pounds, would like a bat that can hit a ball further than 45 feet or can think of something they’d rather have with $20 of birthday money.
The best place to purchase this bat (the 2015 version since the 2014 version is hard to find anymore) is probably here.
