Review on Fly Racing Kinetic Thrive Helmet (Blue/White, X-Large) - Maximum Protection and Style for Riders by Ricky Lahoti

I have found that Fly Kinetic is good for a "round" head profile. It is true. My son and I are both 2XL (53/54 cm). My "medium oval" helmets pinched his ears and came loose above his eyebrows. This helmet fits him perfectly. I didn't notice the difference until I tried this helmet on myself; I could swing it from side to side on my head. For this size; This applies to the size chart. The downward movement of the visor is limited. My son liked the "Rockstar" graphic. It was a good price and good ventilation.
