This is an LS2 Ohm helmet. I wore this ONE time to get my project bike inspected and then put it in storage. It's practically new. It is Snell approved which is why I bought it. Snell standards are supposed to be the most rigorous and it is said that their helmets offer the best possible protection. Usually, Snell helmets cost more... It's a deal.
By the way, I would recommend measuring your head and comparing it to an online chart. I assumed I was a medium and was really a small.
