Yes I try to and icon was the only one that fit exactly right for me… I love my Kali helmet tho it’s almost perfect just a tad bit too loose like the chin strap is not tight at all when in its limit position, I don’t want to buy another icon as I really would like a real helmet, I honestly believe you get what you pay for and in my profession there’s a reason why my tool box is filled with 95% snap on tools and I don’t believe I should cheap out when it comes to something as important as my head ( not that there is much up there after years of brake clean)
If the ICON you are refering to is a Mainframe, then the Corsair V and the RX-Q should fit you well, per wbw’s chart. You can’t go wrong with an Arai if it is within your budget.
