Increase your swing VELOcity with the Rawlings 5150 VELO! The 5150 VELO features an incredibly lightweight design and thinner walls to help young players develop their swing speed and hit the ball further. If a player is having trouble getting a bat around, it will negatively affect their mechanics and ultimately not allow them to hit for power. That's where the VELO comes in. The VELO is made from Rawlings 5150 Alloy that features unmatched durability that provides 10x more strength than traditional alloys. This allows Rawlings to make the barrel walls much thinner to produce a lighter swing weight. But that's not all. Thinner walls also allow for increased barrel flex that results in some of the best trampoline effect of any alloy bat in the game. The precision manufacturing techniques used by Rawlings give players the maximum allowable performance by a youth baseball bat. Maximum allowable performance, increased swing speed, and thin walls will equate to one thing: MORE POWER AT THE PLATE! As with all of Rawlings' premium bats, the 5150 VELO was developed with the help of Sci-Fly Technology. Sci-Fly uses Doppler Radar to track ball flight characteristics and measure the launch angle, ball speed, distance, and spin rate from the point of contact. This information helps Rawlings create a bat with nothing less than optimal performance. Rawlings: Maximum Performance Where it Matters Most on the Field! The 5150 VELO features the USSSA 1.15 BPF Stamp and is approved for play. It is backed by a Full Twelve (12) Month Manufacturer's Warranty. Free Shipping!
