Description

Easton Tantrum 12" Loaded Senior Slow Pitch Softball Bat: ESS5TNTL

Get ready to swing with fury—the Easton Tantrum is designed to let senior sluggers unleash serious power with comfort and control.

Bat Benefits

The Easton Tantrum 12" Loaded SSUSA Slow Pitch Softball Bat is built for senior players who want to generate explosive power without sacrificing feel. With Easton’s Player Optimized Loaded Swing Feel, this bat features a slight end load that helps deliver more mass through the zone, making it ideal for hitters who like to drive the ball with authority. The 12-inch barrel is powered by G4S G4orce Technology, a triple-region barrel system with variable compression that uses a plural resin matrix to optimize flex, performance, and feedback across every part of the barrel.

To elevate comfort and control, the bat includes the CXN MC+ Connection, which works to eliminate unwanted vibration in the handle while ensuring a clean, responsive feel on contact. The Flex 150 Handle adds just the right amount of whip and flex to generate more bat speed and power, while maintaining control throughout the swing. Finally, the Power Boost Soft Knob reduces hand sting and improves comfort—making this bat as smooth to swing as it is powerful. If you’re looking for a senior slow pitch bat that blends cutting-edge tech with a powerful, whip-loaded swing feel, the Tantrum is built to bring the noise.

Warranty

Due to the bat being a high-performing, Senior Slow Pitch Bat; it DOES NOT feature the normal twelve (12) month manufacturer's warranty period from Easton. However, if you wish to do so, you can buy it with our 30 Day Bat Assurance Trial period for a little extra cash.
