Benefits

The helmet’s 21 vents deliver steady airflow to reduce heat build-up on longer rides, while the 300g weight keeps it comfortable over hours in the saddle. The integrated rear LED light has three selectable modes, which improves visibility to traffic when riding at dusk or in poor weather. A removable sun visor shields your eyes from glare and minor trail debris, and the quick one-hand adjustment helps dial in fit on the move.

How to use it

Simple to set up, adjust the rear dial until the helmet sits snug without pinching, and clip the chin strap so two fingers fit under it. If you plan night rides, test the CR2032 battery in the taillight and replace it when dim. It’s a good fit if you want a ventilated, lightweight helmet with added rear visibility, and it makes sense if you prefer a visor for mixed terrain. Ten in mind that certified standards or impact test results are not stated in the product details.
