The only review you need, I really want to find ways to hate but I can’t, I have big as* head and this fit me nicely, I can breath normally and can’t even tell if I have it on my mouth. You can buy some cheap ones as well but it wont be that good as the nb tactical one. If you buy this one, them you’re not gonna need another one. I’m not sponsored to say this but its the best of the best 🤟
