This glove features a single, thick knuckle pad & an open-palm, pre-curved design that allows maximum dexterity. The glove also has an open thumb to increase mobility. The padded lower thumb provides coverage during hits & leaves the upper thumb open for greater movement. The glove also features new Clinch Strapâ ¢ technology. This two-step securing system uses a second, shorter hook/loop strap to help lock the glove in place & reduce movement. The Clinch Strapâ ¢ also creates a larger hand opening to easily slip gloves on & off.
