Get the best for your melon.
Personally, I don't see any reason why you wouldn't spring for the best when your head is involved. I have several POC protection products but the one I wear every ride is the POC Trabec Race. The XL-XXL fits my head perfectly, it has plenty of venting and allows me to mount a light or my GoPRO to it without complication. If the visor was a little more adjustable it would be 6 stars. Very durable. when I got it only the white and orange were available but I have come to appreciate the colors. I get asked about this helmet on almost every ride.
