@Dru, hope you can answer a question for me.
In light of the article in the NYT regarding helmets that accommodate Black equestrians, I wondered about using other helmets (from other sports) which might accommodate more sizes.
I notice that helmets for skateboarding do come in larger sizes, and, reading a little bit about the ASTM standards, are tested at even higher heights than riding helmets. What else in the ASTM standard is different between these two types? Would these be suitable for riders looking for an option?
