Which Fox size am I?
Measure your head first (tape or string around the widest part, 1-2 cm above the eyebrows), then read it off the table above — Fox sizing is not the same as the next brand's. Across the range, Fox covers 51 to 63 cm (20.1 to 24.8 in). If your measurement falls outside that, no Fox helmet we track will fit you.
