Ok here we go... My explanation for Flash's suit.
-As I mentioned, when Barry runs he emits electricity. The faster he runs the more he gives off. This can be quite dangerous to by standers if he full out gets it. So at first he doesn't know this when he learns his powers and he finds out by watching the news that several people where "injured" by a zooming lighting ball.
-Like in the 90s series he meets someone at STAR LABS to help with this condition, so the person shows him the "Storm Solider Suit." The purpose of the suit was originally for storm researchers who could skydive into a thunder storm with the suit on and actually be struck by lightning and be unharmed to collect data. The yellow parts of the suit are metal to attract the lightning. Like everything else the Army wants to utilize this and use it for soldiers so they can parajump through storms and surprise the enemy, where as a regular parajumper could not.
This suit is the "Storm soldier suit"

But use THIS mask in place of the one above.

Also at first the mouth area is not open. It has a mouth breather that fits over the enitre mouth opening for high altitude jumps. Like so.

-Now, Barry with the suit on tests it out. The metal on the suit acts as a conductor and attracts the electricity that Barry puts out and keeps it from shooting all over the place. Even the swooshes (or whatever they are called) can still be kept to please the fanboys. So while Barry is running he starts to get dizzy and slows down and almost passes out. He figures out that the oxygen mask is restricting the air flow to his mouth and takes JUST THE MOUTH BREATHER PORTION OFF that way we get the classic mask.
He tries it again and to the STAR LABS employees surprise Barry doesn't get bombarded with bugs or anything in the air because when Barry is running his aura is electrified so anything little this like so that comes close to his skin is zapped allowing him the air he needs and the protection from bugs and such.
So one day he saves someone with the suit on because if he REALLY runs in anything else it burns off and the person said someone came in like a flash of lighting. So being the fanboy that Barry is he puts the logo on the suit in honor of his hero growing up Jay Garrick, the worlds fastest Olympic sprinter from his childhood.
So what do you think? And feel free to be as harsh as you want I'm grown I can handle it lol.
