WHAT HEAD SIZE DOES THE ADJUSTABLE RUNNING CAP FIT?
Adjusts to your head size with rip-tab strap at the rear of the cap: suited to head sizes between 54 and 58cm.
The elastic rip-tab allows you to adjust the cap 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.
