I have a project where I need to modify the helmet foam to get a better fit on an odd shaped head. I have looked on the web for fit kits and such, but none will meet my needs very well. I was hoping that someone here might have a good idea where to find the urethan foam with laminated wicking / antimicrobial fabric like you see in batting helmets and for that matter the whole aisle of helmets at the sporting good store. I would likely need less than a square yard depending on the thickness.
I k now it is probably a mediocre idea at best to fiddle with a helmet design, but I need to bulk up the sides to keep the helmet from fitting floppy from side to side.
