COMBAT's new Portent XL is not just any big barrel bat. With it's enlarged 2 3/4 inch barrel, the Portent XL has a HUGE hitting surface and COMBAT's new FULL BARREL SWEETSPOT! Yes, you read that right. There is no such thing as a mishit with this bat, 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 sweet spot area where absolute maximum performance can be achieved! The 100% composite, one-piece Portent XL 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! SmartFlex and SmartPly technologies work together to make this the smartest bat ever constructed. The result is a continuous store-and-release monster that will allow players to think beyond the warning track, beyond the wall, and beyond the park. COMBAT: For Players, By Players. The Portent XL features the USSSA 1.15 BPF Stamp. It is backed by a Full Twelve (12) Month Manufacturer's Warranty.
