Giro Savant Cycling Helmet

This is my 3rd helmeet and by far, it is the most comfy, LIGHT, and secure. If u measure your head and follow the by the size charts, I feel THE size guide is true to size. I have a pretty small head (measuring at 21.5 finches) and I ordered a size S. Helmet fits great and is not too tight. In the past, I ordered a size up to be on the safe side, but even after I tightened to the max, I felt helmet wasn''t as secure as it should be. If I were to crash (not that I ever plan on it), helmet wouldn''t have stayed on. This helmet defintely would and will protect my head. The matte black is really sharp looking too .
