The Airframe Pro Carbon is one of the lighter helmets on the market at 3.42 pounds and meets DOT FMVSS 218 and ECE 22-05 standards. Comfort is excellent, especially after tailoring the fitment with the alternate liners. Ventilation is very good, though cooling feel is limited to the forehead and back of the head. Aerodynamics are excellent when pointed straight ahead with very little buffeting, but turning your head to check over your shoulder causes some strain on your neck. Visibility out the eyeport was very good, even in a full tuck, and the face shields remained fog-free and sealed well with no noisy leaks. We weren’t that fond of changing shields, however, as lining up the tabs in the pivot mechanism was often difficult, and the cheap snap-in outer covers over the pivot require a lot of effort to remove and reinstall. And the removable breath deflector and chin curtain both had a tendency to come loose if you weren’t careful handling the helmet.
