WARNING TAIL LIGHT
The ROCKBROS helmet is equipped with tail light to ensure the safety of the rider during the ride. It protects night riders and effectively avoids most safety hazards on the road. The tail light provides three flashing modes, which can be adjusted according to different situations.
UV400 PHOTOCHROMIC LENSES
The ROCKBROS photochromic lenses become brighter or darker depending on the effect of ultraviolet rays. The lenses can protect your eyes from UVA, UVB and UVC radiation during cycling
SUN VISOR FOR FACE PROTECTION
The helmet is equipped with a sun visor that offers additional protection for the rider's face. It shields against mud, branches, and debris, preventing them from hitting the rider's eyes and face.
THICKENED LINER AND INSECT NET
The interior of the helmet has a thicker liner that enhances sweat absorption, breathability, and shock absorption. The liner can be easily removed for cleaning thanks to a hook-and-loop design. For added comfort, the helmet also features an anti-insect mesh in the ventilation holes to prevent small insects from entering the helmet.
FLEXIBLE AND ADJUSTABLE FIT
The helmet comes with one-handed adjustable dial knob system that allows for easy resizing to fit the rider's head circumference. This ensures a secure and personalized fit. The helmet size is 55-62CM, so it's important to measure your head before purchasing to ensure the proper fit.
