With all the helmet shopping that I've been doing lately, I couldn't help but noticed that many of the helmet company logos look rather similar. The biggest offenders are HJC and KBC. Except for the letter, the designs of their logos are nearly identical. OGK, Suomy, and Arai all feature a rather flat oval with their letters of the company inside.
Makes things a little annoying when I'm trying to choose a particular type of brand.
