Overview

Swinging a balanced composite fastpitch bat with a gapped barrel wall is the idea behind the Kryo. A patented barrel system with an internal disc works with the XPND End Cap to grow the sweet spot.

Louisville Slugger pitches the Kryo as the largest sweet spot ever on its fastpitch bats. A cushioned grip and a balanced swing weight aim to help all types of hitters make steady contact. The title lists four drop weights, while the description names one.

Who it's for

Hitters of all skill levels who like a balanced swing are the target. Anyone playing under a specific league rule should check certification first.

Pros and cons

Pros
  • Balanced swing weight
  • Two piece composite
  • Large sweet spot claim
Cons
  • Drop weight stated inconsistently
  • Certifications not named

Performance notes

A gapped barrel wall and an internal disc system flex together on contact, and the end cap works with them to widen the effective hitting area. Balance in the swing weight helps the barrel come through the zone under control.
