Technologies used

In this chapter we explain the technologies that the manufacturer uses in this product.

IN-MOLD CONSTRUCTION
With the in-mold construction, the robust polycarbonate outer shell is glued to the impact-absorbing EPS inner shell in one step while it is foaming. The helmet becomes even more resistant, without additional weight. This production process also makes it possible to form significantly better ventilation systems and vents. Compared to traditional helmets, in-mold helmets are lighter and have significantly better ventilation systems.

MIPS Spherical
MIPS Spherical is the further development of the Multi-Directional Impact Protection system. Manufactured in the typical design, the two layers of EPP foam in two degrees of hardness act as a kind of joint that can move a few millimeters in any direction, effectively reducing the rotational energy at certain impact angles.

FIDLOCK® MAGNETIC CLOSURE
The FIDLOCK® magnetic closure closes automatically and can be easily opened again by sliding sideways with just two fingers. Operation with just one hand is quick and effortless, even when wearing gloves.

MIPS
The MIPS® safety system is designed to provide additional protection for helmets in a variety of accidents. In certain impact situations, the MIPS system can reduce dangerous forces that might otherwise be transmitted to the helmet wearer's head.

1. Conventional helmets are designed and tested for straight impact. However, in most cases the impact occurs at an angle, which can cause rotational movements to the head.

2. These rotational movements can cause brain injuries.

3. The low-friction shell is intended to help reduce rotational movements to the head in certain cases of oblique impact.

Straight impact - oblique impact

The brain is typically more sensitive to rotational motion than linear motion because it has similar shear strength to water or gel. When rotational motion causes different areas of the brain to move away from one another, the tissue can be stretched, causing concussions or other brain injuries.

Rotational motion is a common cause of concussions and more severe brain injuries from an oblique impact to the head. The MIPS system consists of a low-friction shell that is attached inside the helmet. The low-friction shell is designed to slide slightly inside the helmet in the event of an accident, allowing forces to be directed away from the head. It is intended to help reduce the risk of brain injuries.

Most traditional helmets are designed for a straight impact, but in most cases the impact occurs at an angle. The low-friction shell can reduce the rotational forces of an oblique impact.

Security system based on the brain

Unlike traditional helmets, which are designed and tested primarily for straight impact, the MIPS system's low-friction shell mimics the brain's own protection system against rotational motion. The cerebrospinal fluid is our natural protective system that allows the brain to move offset from the skull.
