Hey guys, wats up? I am going to do a no gi tournament sometime in the future and have a few questions. First off, can you do it in teen divison with wrestling headgear? (im starting to develop cauliflower ear). Also whats the difference between compression shirts/shorts and a rashguard? And what should I wear for my bottom? Shorts? Vale tudo shorts? Or do they have rash guard shorts? Also are cups allowed? Because when im sweeping someone, they always end up kneeing on my groin. Thanks for the help guys, take care!
