Dude, we live in Yuma/San Luis! Just think how hot it is out (Its only going to get hotter too!) and how much it would suck to wear a helmet while running around. Its going to be way heavier than a boonie for sure. Go with an ACU boonie. That is what we all wear out in the sun. You might have noticed at the last skirmish. If you want a helmet, get it, but we are not that serious about the milsim aspect of the game and you'll be the only one wearing one. If you want to be comfortable and fit in, go with the boonie. PM dismount and see if he has any ACU stuff he wants to sell. I know he has a bunch of it.
