For those players that started with a small barrel COMBAT - you will not be disappointed in the all new B4 youth big barrel bat. For those of you that have never experienced the COMBAT difference, here is what you can expect: a swing weight that is right on point, a sweet spot that's almost not even fair, and zero sting/vibration. And that's just the tip of the iceberg. It all starts with COMBAT's Localized Stiffening Technology that allows their engineers to lower barrel wall stiffness on both sides of the normal sweet spot, resulting in an enlarged Double Sweetspot area where absolute maximum performance can be achieved! The 100% composite, one-piece Portent utilizes COMBAT's Blended Fiber Technology that blends several different fibers in varying proportions at carefully controlled angles to create a composite material that results in both resilient durability and increased trampoline effect. Separation Barrier Technology also allows this bat to be HOT out of the wrapper! The B4 Portent draws much of its durability from its Seamless Construction; meaning that there are not cuts or splices - just continuous fiber all the way around. Feel, Durability, and Sweet Spot. That's what makes COMBAT the preferred composite bat. COMBAT: For Players, By Players! The Portent features the new USSSA 1.15 BPF Stamp. It is backed by a Full Twelve (12) Month Manufacturer's Warranty.
