WHAT HEAD SIZE DOES THE ADJUSTABLE RUNNING VISOR FIT?
Adjusts to your head size with rip-tab strap at the rear of the visor: suited to head sizes between 50 and 62 cm.
The elastic rip-tab allows you to adjust the visor to your head size without feeling compressed for optimal comfort.
To measure your head size, place a tape measure above your eyebrows. Make sure it is parallel to the ground when your head is straight.
