While the baseball model gained the most notoriety, the "Stealth" brand spanned several sports in 2009:
: The extreme performance and safety concerns surrounding bats like the 2009 Stealth led the NCAA and NFHS to develop the BBCOR (Batted Ball Coefficient of Restitution) standard. This new standard was designed to make non-wood bats perform more like traditional wood bats, effectively ending the era of "firesticks" like the Stealth. Core Technologies
: Used to strengthen composite structures, allowing for thinner barrel walls and a larger sweet spot. 2009 stealth bat
The 2009 Stealth series utilized several patented technologies that made it a "weapon" on the field:
: In 2008 and 2009, college baseball offensive statistics exploded. Home run records were shattered, and routine line drives became dangerous to pitchers due to skyrocketing exit velocities. While the baseball model gained the most notoriety,
The 2009 model represented the peak of the (Ball Exit Speed Ratio) era. Its performance was characterized by a massive "trampoline effect" that actually improved over time as the composite fibers broke in.
: A two-piece design that acted like a hinge, providing efficient energy transfer from handle to barrel while eliminating hand "sting". Its performance was characterized by a massive "trampoline
: Optimized the relationship between composite materials and manufacturing to maximize "pop". 2009 Product Line Variations
