Quick Release System Scratch Resistant UV Resistant Fog Resistant Pinlock Max Vision Ready Quick Release Strap Certified: ECE 22.05 HELMET SIZING Measuring your head for helmet fitment is the right place to start, but it is only a guideline. Different shapes of heads might require a slightly smaller or larger helmet in any given model. Trying on the model you are interested in is always recommended. A helmet should be as snug as possible, without being so tight that it will give you a headache. It’s best to be fitted by a professional.
