Helmets
Measure horizontally around the widest part of your head, just above the eyebrows, using a soft tape. Compare the measurement with the chart on the exact model page. If possible, try the helmet on; if between sizes, contact us with your measurement before ordering.
Riding apparel
Measure your chest and waist over a light layer; for pants, also note your hip and inseam measurements. Send those measurements, your height and the model number. The supplier’s letter sizes vary by model.
