Well, I thought about the heat factor from wearing this material. I usually play wearing a long sleeve under armor shirt (lol..under amor), and think I will be wearing it with this vest when I play, and maybe a light t-shirt. Back to the helmet concept. I you made a practical use paintball helm based off a mando, it can either go two ways. First, you will have to be a kick ass player cause you'll look like a baffoon if you suck really bad, or second, if you suck really bad, dont take off the helmet, cause no one will know who the heck you are. I imagine that a mando helm in paintball if done right can give some serious head protection. I hate getting hit in the head. I have seen some masks out on sale that are full head covers, so I imagin you could do the same with a mando bucket. You also have to consider a good enough lens, that is hard to fog, as well as a good venting system cause it will get hot in that thing. Good luck, wouldnt mind seeing something like it being made.
