The 4TH generation of the ONX X-Factor Training Glove has been slightly adjusted to offer better fit, feel and comfort for the wearer. This improved X-Factor design provides the desired support of the wrist, carpal and metacarpal bones in the hand, and supports your grip and hand position when you need it most. The patented internal strapping system allows for adjustable sizing and support, and is the first wrap-less glove on the market. The technology in the X-Factor Gloves provides the versatility a boxer or mixed martial artist wants in a training glove, and works great for sparring, bag & mitt work. Watch this short video above by Trevor Wittman, World Championship Coach & ONX Founder, that explains in more detail the benefits of using these ONX gloves.
