I swear I saw someone wearing one of those in SF - somewhere around Scuderia - about a month ago! It looked identical. Maybe he got his hands on a prototype. I thought it was one of the cooler things I had seen in a while and was left wondering where I could find such a helmet. Very hooligan looking and It looked great for riding around town, when you never know when you'll be riding west at 6:30pm. I think I'm gonna have to put an order in for one of those...
I definitely wouldn't want to use it at speed though, as the article mentions.
it may indeed replace two helmets, or three, or four... you could buy two off road lids and a decent on road lid at that price.
it may seem like a great idea but i'd rather keep the two seperate; don't need a swiss army knife for a helmet that's going to get knocked around in the bush and sure as hell don't like the idea of paying $500 for one either.
imo it's about as useful as no internet sales... and points out once again the folks at arai are living a dream.
