This is a BRAND NEW/NEVER USED Louisville Slugger Kryo Fastpitch Bat 2025 (-10) (31" and 21 oz with a barrel diameter of 2 1/4"). It features a 2-piece composite construction and is dark blue with black grip tape. It was bought in July of 2025 and was unwrapped but has never hit a ball/been broken in. It has been kept safely and has no scratches or marks. This is also one of the best bats currently on the market!! Also I know the price may seem high but I am heading off to college next year and every bit saved helps!

Perfect bat for:

Players who prioritize consistent contact and a comfortable feel.

Durability

Control

The Louisville Slugger Kyro fastpitch softball bat has a balanced swing weight making it suitable for hitters of all levels, while the patented GO-EX1 Barrel System and XPND End Cap combine to create the largest sweet spot ever on a Louisville Slugger fastpitch bat. The VTX Connection System allows for independent movement between the barrel and handle for a best-in-class feel with less vibration on contact.

“

Ready to go. The new Kyro is very durable. It's hot out the wrapper. My daughter loves the grip and the sound it makes. Just be aware it's a bit heavier than listed, but my daughter loves it.
