No Wiggle Fit – Flexlock Fit system and 17-piece padding kit ensure a fully adjustable, secure fit to hug your head no matter how hard or big you spin.

Pro Tip – Pro-Tec strongly recommends sizing up if your measurements fall at the upper end of a size range. Example: If you measure 54 cm, choose size S/M. Based on years of customer feedback, the larger size typically offers a better, more comfortable fit.
