Diamond MMA's Alex Coriano hit a night time roll with 155-pound champ Gilbert Melendez and TUF 5 winner Nate Diaz. Coriano wrestled at Purdue and designs our cups to keep fighter jewel's safe on fight night, whether they are on FOX in title fights like these guys or wearing thai shorts or wrestling singlets. If you don't see Diamond MMA in your gym, you might be in for some unnecessary pain. Train safe, fight hard, protect ya' neck, protect your nuts.
