The name Primo means be the best and thats what this bat is. Designed using a 14 Barrel for maximum hitting surface this bat is designed for players of all calibers. This Primo is different than previous models. It features E-Flex 360 Barrels made from Mikens Explosive C4 Carbon Fiber Technology. E-Flex 360 was developed to offer a more consistent and durable barrel, while providing the same explosive feel you love. The Primo Maxload features a .5oz end load to maximize swing speed for homerun hitters. We also added Miken F4P technology to our handles which improves energy transfer and reduces the amount of shock during impact. Also new for 2021 is the A1 Knob which is a smaller knob design for players who like to wrap their hand around the knob during their swing.
