The name Primo signifies "be the best," and that's exactly what this bat embodies. Crafted with a 14" barrel for maximum hitting surface, this bat is suitable for players of all levels. This Primo model differs from previous versions, featuring E-Flex 360 Barrels made from Miken's Explosive C4 Carbon Fiber Technology. E-Flex 360 was developed to provide a more consistent and durable barrel while maintaining the explosive feel you love. The Primo Maxload includes a .5oz end load to enhance swing speed for home run hitters. We've also incorporated Miken F4P technology into our handles to improve energy transfer and reduce shock during impact. New for 2021 is the A1 Knob, a smaller knob design for players who prefer to wrap their hand around the knob during their swing.
