Solid Safety Ratings: The EXO R1 Air is both DOT (US standard) and ECE (European standard) certified
The independent testing done at Virginia Tech offers a fantastic resource for identifying the safest adult helmets on the market
Some brands, such as Specialized, have dived in wholesale and you'll see a rating for most of their helmets other brands have been more circumspect
From the first moment, you can tell it's a well-designed helmet: it's comfortable, weighs almost nothing, and fits very well, even on long rides where you normally end up with a sore neck
Thoroughly impressed and pleased with my purchase
Off-Axis Frostbite Edges - Edges beneath your bindings extend out slightly for tremendous edge-hold on hard, icy conditions
