Pro-Tec Low Pro

Groundbreaking technology for an exceptionally deep fit with unlimited customization options for maximum comfort and secure hold. Slim, Deep Fit: The Slimtech Core with EPS matrix foam is 22% thinner than a conventional helmet, providing an extremely sleek, deep fit. No Wiggle Fit: The Flexlock Fit system combined with the 17-piece padding kit allows for a fully adjustable, secure fit that hugs the head tightly, no matter how hard or far you turn. Reliable and safe: Triple certified according to the US safety standard CPSC for bicycle helmets (from 5 years), ASTM F1447 for recreational cycling and roller skating, ASTM F1492 for skateboarding and trick roller skating. Sizes: XS/S: 51-54 cm | S/M: 53-57 cm | L/XL: 57-60 cm | XL/XXL: 60-63 cm. Pro tip: If your head circumference is at the upper end of a size, we strongly recommend choosing the larger size. For example: At 54 cm, choose S/M. Our long-standing experience shows that the larger size usually fits more comfortably.
