What Makes the Genesis Viper a Game-Changer?
The 2025 Genesis Viper isn’t just a new release—it’s a reinvention of what a slowpitch bat can be. Designed for players who demand elite-level performance, this model merges new composite technologies, a precisely engineered swing weight, and bold aesthetics into a bat that delivers with every swing.
Here’s what you need to know:
Key Features
1. NEW 1-Piece / 13” Barrel Construction
The Viper features a 13-inch barrel crafted using SSP-PowerTech Composite, a breakthrough material upgrade designed specifically for 240-compliant bats. This one-piece design increases stiffness and barrel integrity, resulting in better energy transfer and more explosive exit velocity off the bat. The stiffer handle creates a responsive feel that power hitters crave, allowing you to drive through the zone with conviction.
2. Double-Wall Barrel with Reinforced Sleeve
Beneath the surface, the Viper’s double-wall barrel structure includes a stiff inner wall that maximizes trampoline effect while preserving barrel durability. The reinforced sleeve profile has been carefully engineered to create a massive sweet spot and long-lasting performance, even in demanding hitting conditions.
3. Perfectly Tuned End Load Swing Weight
Whether you’re a seasoned slugger or a rising power hitter, the end-loaded swing weight delivers that extra oomph without compromising swing speed. Louisville has struck the perfect balance between a manageable feel and added barrel mass—creating an explosive launch angle and more carry on your hits.
This bat is built for players who love that heavy, end-loaded feel and know how to use it to send balls flying deep into the outfield.
4. Patented XPND End Cap
At the core of the Viper’s performance is Louisville’s XPND end cap—a patented design that allows the barrel to "float" and flex more efficiently on contact. This innovation improves feedback, maximizes the barrel’s performance zone, and adds that extra bit of pop you can feel in your hands and hear in the crack of the bat.
5. Removable Pyramid Grip Taper
Every detail counts when you're at the plate. The LS Removable Pyramid Grip Taper gives players superior comfort, control, and a secure feel throughout the swing. Whether you prefer a tighter grip or a more relaxed hand position, the removable taper lets you customize your handle for optimal performance.
Design That Bites Back
The Genesis Viper doesn't just perform—it demands attention. With a custom snakeskin graphic slithering down the barrel, this bat is one of the boldest visual statements in the 2025 lineup. It’s a look that says you're not just here to play—you're here to dominate.
Durability You Can Trust
Built to last, the Genesis Viper is constructed from lightweight, high-strength composite materials that hold up swing after swing, game after game. Whether you're playing in tournaments or rec leagues, this bat is designed for consistent performance and season-long reliability.
And if that’s not enough peace of mind, Louisville Slugger backs the Viper with a One-Year Manufacturer’s Warranty.
