ONE SIZE: Fits head circumference from 21 to 23 inches (54-58 cm) - PLEASE MEASURE YOUR HEAT FOR A PERFECT FIT! PLEASE NOTE THAT THIS IS NOT A VERY BIG HELMET (8.5 x 12.5).

VISOR: The magnetically fastened shield provides wraparound eye (UV) protection and it’s easy to flip up or remove with one hand when appropriate. (PLEASE NOTE: The visor can only be attached while wearing the helmet (NOT BEFORE YOU ARE PUTTING ON THE HELMET) and can only be detached while you are wearing the helmet - YOU CAN NOT TAKE THE HELMET OFF WITH THE VISOR ATTACHED TO IT). WEARING THE HELMET WITH VISOR WILL BE A TIGHT FIT AND THIS SETUP MAY NOT FIT A LARGER SIZE HEAD OR FACIAL FEATURES.

KEEPING YOU COOL: Your aero cycling helmet is equipped with a total of 8 vents: 4 in the front and 4 in the back, offering optimal airflow and minimal wind resistance to keep you cool during a race and stay more comfortable without sweat all over the head.

FEATHERWEIGHT: With a helmet weight of 279 gms (with shield) you’ll soon forget that you’ve even got a helmet on your head- until you need it! This helmet is about 25% lighter and smaller ( 8.5 x 12.5) than other aero helmets.

HARDSHELL: Tough on the outside, soft on the inside, just like nature intended. Our low friction, abrasion resistant PET outer shell is designed to slip and slide in the event of a crash; helping to minimize the risk of torsion injuries. This helmet is CSPC certified.
