The Miken 2025 Freak Slowpitch Softball Bat is a composite bat designed for slowpitch players looking for a powerful and balanced option.

This makes it a good choice if you want a bit more pop in your swing without feeling too heavy at the handle.

The bat also uses V2 Flex Barrel Technology, which means the barrel has a multi-layer design to create a bigger sweet spot, helping you make more solid contact even if your timing isn’t perfect. The mid flex handle balances stiffness and flex, offering a comfortable swing that isn’t too stiff or too loose. The ergonomic A1 knob helps with grip and control, making it easier to swing the bat precisely.

The V²-Flex barrel technology extends the sweet spot, making it easier to connect well even if your swing isn't perfect every time. The stiff Pro Flex handle keeps the bat stable during your swing, helping create faster ball exit speeds, while the smaller ergonomic knob improves comfort and control.
