I purchased the orange medium helmet on a BTD sale. That's where the value rating comes from. I wear a medium Giro and Specialized and this fits the same. It has a strange feel to the inner cage when you first set it on your head but nothing noticeable once it's locked down and it stays put. Wearing it on the road mostly. Has a real leather chin strap, that may be a problem for some. Visor is a must for me, I'll sacrifice a stiff neck to prevent a burnt nose any day. Did I mention It's lightweight ?
