SAFETY: To achieve a solidly constructed bicycle helmet, we follow three crucial steps. First, the exterior shell is placed in the mold, then it is reinforced with a skeleton, and finally, the foam is added to hold all the parts firmly connected. This ensures the rider's safety in the event of an accident.

COMFORT AND VENTILATION: The inner pads provide a comfortable wearing experience, and they can be removed when the rider wants to clean them. The specialized ventilation design allows air to flow through the helmet, which can help increase speed and keep the rider cool.

This means that if the helmet doesn't fit right, it will be replaced immediately or the money will be refunded.
