The lightweight design of these mitts gives fighters the ability to work rapid combinations for extended rounds. The air center helps disperse the impact without adding any additional weight to the mitts, while the hook and loop strap allows for quick movement without any disruption of the punch mitts' placement. These mitts have an outer layer of Ring to Cage's GelTech padding, further dispersing any impact. If you've never experienced air-pocket punch mitts, it's certainly a unique and desirable addition to any training regimen.
