Circumference adjust technology - the helmet only protects if it is correctly fitted and has the correct size. However, it is not possible to make a helmet that would be suitable for all sizes and shapes of the head it is supposed to protect. Therefore, helmets are usually produced in two basic sizes, and for accurate size adjustment, an adjustment system is used, usually located in the back of the helmet, which allows you to fine-tune the size of the helmet so that the helmet does not press, but at the same time holds firmly on the head.

HQBC helmets use different types of swivel systems that are reliable, easy to access and adjustable with two fingers. In addition, most systems allow, in addition to size adjustment, system height adjustment in two or three positions. Adjusting the height of the rear clamp is important for both comfort and safety. By adjusting the height of the system upwards, you can prevent the pressure of the entire fastening behind the ears, or by moving it downwards, you can allow a tighter fit of the helmet.

PVC shell - PVC (Polyvinyl Chloride) is used as a material for the helmet shell, mainly for more economical models. The shell and body of the helmet are produced separately and are joined by gluing during the production process. It is the oldest helmet production technology and is mainly used for children's helmets. PVC is not resistant to high temperatures and is damaged at temperatures higher than 70°C.

Reflective technology - in addition to head protection, helmets should also contribute to the rider's overall safety, which is especially important in poor visibility and low light conditions. HQBC helmets are equipped with reflective elements in the back of the helmet or on the fastening mechanism.
