Official FIGHTING NEXUS Mixed Martial Arts Gloves These are the OF gloves actually used by fighters in NEXUS. In addition to the traditional fit of the COBRA open-finger gloves, the cushioning has been thickened to reduce the burden on the fists. This allows for safer training. Named Professional Type, they are made with an emphasis on durability so they can be used for rigorous training. Made of genuine leather. The more you use them, the more they will conform to your fists.
