A Snell rated helmet has more proof that it's been tested, and meets Snell's standards, but these helmets were actually tested by David Thom and Harry Hurt, both of whom said that they did meet DOT standards, and that DOT standards are better than Snell standards. Snell obviously disagrees with this, but considering the fact that these two guys have been testing helmets for decades, and are the most respected people in the field, I'll still take their advice over that of anyone from Snell. I have a copy of the Hurt Report, which I got when it first came out, not to long after I started riding motorcycles on the street. I admire the Snell Foundation for what they are doing, but I think their standards need to be changed a bit. And just as one more piece of evidence, I also emailed Art Friedman, longtime and well known editor of many motorcycle magazines, and a believer in motorcycle safety, who has racked up more 2 wheeled miles than I will ever come close to, and he agrees with the information in that article as well. Friedman has has a long relationship with Harry Hurt and David Thom, going back to the '70s. The Snell sticker has long been an important consideration in buying a helmet, and I have bought several helmets because of it. But the opinions of three of the most reputable people in the business has changed my mind about that, and I hope that Snell revises it's standards, which it will, if it's true purpose is protecting people in motorcycle accidents, and not just helping to sell helmets. Peace. Jerry.
