Scratch resistant paint
Each shell, after being smoothed, is given several layers of varnish. The outer shell is then coated with a transparent, scratch-resistant varnish. This makes the helmet less prone to damage.
Integrated sun visor
The integrated sun visor is easy to use. By pulling the lever of the visor, the visor comes down. This way, you don't have to wear sunglasses on sunny days. The sun visor blocks most of the sun's rays and can be combined with sunglasses. When it gets too dark, you can easily pull the visor up again and use the transparent visor.
Luxury inner lining
The inner lining is more luxurious compared to the standard lining. The lining is made of refined materials and has a luxurious look. The colours of the lining match the exterior of the helmet. The luxury lining can often be found on the more expensive helmets.
Removable inner lining
The inner lining is attached to the inner shell by snaps or velcro. The removable inner lining can be washed with neutral soap. In this way, the lining remains in good quality and the helmet fresh. In addition to the inner lining, the cheek pads are also removable.
Perforated inner lining
The ventilation system in the helmet ensures a constant air flow. Through the perforated inner lining, this air, which enters through the air channels, can also reach the skin. This way it always stays cool inside the helmet. In winter, the ventilation system can be closed so no air enters the helmet.
Extra soft inner lining
By using softer materials compared to the standard lining, the helmet provides even more comfort. During a long ride, the soft lining is absolutely noticeable.
Micrometric buckle
The micrometric buckle is the most frequently used buckle on helmets and easy to use. The rattle buckle ensures that it can be adjusted to the correct position. The buckle is easily opened by pulling the red loop.
Anti-theft ring
The chin strap of the helmet is equipped with a metal ring. By using this ring, the helmet can be attached to the hook under the saddle. In this way, theft is prevented.
Goggles fixation
On the back of the helmet, there is a leather strap with a press stud. The elastic of the helmet goggles can be threaded through here. In this way, the elastic strap stays on the helmet while riding.
Average weight size M +/-1100gr
The weight of the helmet depends on the type of helmet. A jet-helmet is generally lighter than a system helmet. Glass fibre is also lighter than polycarbonate. The helmet is often measured in size M without visor. The second number on the sticker at the back of the helmet indicates the weight of the visor.
Sizes XS-S-M-L-XL-XXL
The size of the helmet is determined by the number of centimeters of head circumference. The size is measured with a measuring tape above the ears along the widest part of the head. The number of centimeters determines the size. The sizes are however an indication. This is no guarantee that the helmet will fit.

Different shell sizes
By using different helmet shells the helmets get an even better fit. The smaller helmet shells are used for the smaller sizes and the larger helmet shells for the larger sizes. In this way, size XS has a smaller helmet shell than size XXL.
Fiberglass shell
In general, glass fiber helmets are more expensive than polycarbonate helmets. Glass fiber is highly resistant to weather conditions and UV-light. By using glass fiber, the helmet is also much lighter and the impact is better absorbed during an accident. The lifetime of a glass fiber helmet is on average between 8-10 years (provided the helmet is used properly).Specifications
