Specifically folliculitis? I was wondering if the guys with more/longer body hair find their hair follicles have more chance of being opened ? And if yes would a rash guard help in anyway? I have been looking more and more into staph and it's treatments and peoples theories behind them. I know the rash guard theory is along shot but if there is less hair to pull I was thinking it may make it harder for the hair follicles to be pulled open. So to counter the opening of the hair follicles I was thinking maybe a long sleeve rash guard could help ,given their would be a gi over the top of it in the case of gi classes. Having never worn a rash guard I was wondering ,while they appear skin tight do they move much? If you have a gi over the top does the gi freely slide over the rash guard when grappling or does it tend to stick and create friction on the body ? are rash guards just rash guards or are there certain things one needs to look for. I know people who surf and they just opt for generic ones, does the same apply for MA's?
