Thanks for this heads up!
I've been needing to get a new helmet for my lesson kids and I haven't worn my helmet in years because the shape of it isn't oval enough for my head and therefore gives me headaches. Because of this post I went investigating at my favorite horse stuff website and ended up buying "my" kids a new children's helmet and I found my favorite style of helmet, marketed for oval heads, for a steal!
Bam! Safety all around.
