Hands down these are Hayabusa's premier fight shorts. The Chikara Recast edition shorts are equipped with pretty much every premium performance spec in the Hayabusa lineup.
Built from their impressive Mechanical PolyDirectional Stretch Fabric, which is aided by the split reinforced side vents and lets you move freely and uninhibited. Adjusted by Hayabusa's innovative web tie internal string system. The GuardLock interior grip lining throughout the waistband ensures that no matter how much you scramble, your shorts will stay safely in place. No shifting, no twisting, no sliding down/up.
Finished with T3 stitching so you can be confident that your movement is not going to be impeded and your shorts are not going to be in danger of failing.
