I've always been skeptical of Icon's quality. Thought they more form over function. But when my oldest kid, who only wears Icon, got hit, I reconsidered. He did not have ANY road rash, despite only wearing a t-shirt, shorts, running shoes, and gloves. But, he had a minor concussion, broken rib(s) & wrist, torn ACL/PCL/MCL on his left leg, and a weird gash on his right knee. This was obviously a sudden stop crash; from 40 mph. His Icon helmet....I could hardly find where it hit the pavement; although the face shield was gone. So, for a helmet that cost less than half of my ARAI, it did exactly what it was supposed to. Needles to say, the helmet was removed from service; replaced by another Icon.
Would my high dollar Arai prevented the minor concussion? No telling. And according to that article, considering my age, it may not matter any way.
Oh yeah, my kid? 100% recovery, and completed rehab six month early. And, less than 9 months after the crash, he passed the Ft Worth PD physical, and completed their 8 month academy. And, although at his age he doesn't realize how luck he was, I do after seeing as many crashes that I have.
MY philosophy? Buy the best helmet that you can afford. That article confirms what I had started noticing....even the "cheep" helmet are getting better than we realize. Once again, just my two cents.
