Man there has to be something. My motorcycle helmet when I used to ride was a HJC XXXL and I still had to smash in the foam in the front a tad. My head's all messed up shaped on the top. I'm the elephant man. I think an adult football helmet would work very well and drain amazing. Even has the bar in the middle of face mask to ward off the hand pole.
I have yet to find a football helmet here in town and lacrosse helmets look dorky, football helmets are a classic!
