Giro Helios Spherical helmet

State-of-the-art performance for speed and adventure

A helmet perfect for road or gravel adventures. The main component of the special design and performance of the Helios™ is undoubtedly the Spherical technology. This uses the technology of the market leader MIPS®. The specialist in head and brain protection. This technology allows the outer helmet inner shell to rotate inside in the event of a fall. At the same time, the progressive layering system of the two shells ensures comprehensive protection and performance.

Giro's patented Roc Loc 5 Air Fit system also improves the ventilation of the Helios™ with 15 vents. The antimicrobial Ionic+ padding not only has the highest antimicrobial sweat absorption properties, but also ensures maximum comfort.

Technologies used

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

Nanobead EPS Foam
To achieve a slim silhouette without compromising protection standards, the Aether uses a microbeaded expanded polystyrene.

ROC LOC® 5 Air
In addition to the optimized air circulation of the Roc Loc Air System, the vertical positioning can be improved through asymmetrical adjustment at the contact points.

MIPS
The MIPS® safety system was developed to provide additional protection for helmets in numerous 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 a straight impact. In most cases, however, the impact is at an angle, which can cause rotational movements for the head.

2. This rotational movement can cause brain injury.

3. The low-friction shell is designed to help reduce rotational movement of the head in certain cases of angled impact.

Straight impact - oblique impact

The brain is typically more sensitive to rotational movement than linear movement because it has a shear strength similar to that of water or gel. When rotational movement causes different parts of the brain to move at different times, the tissues can be stretched, causing concussions or other brain injuries.

Rotational motion is a common cause of concussion and more serious brain injury from an oblique impact to the head. The MIPS system consists of a low-friction shell that is fixed 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 said to help reduce the risk of brain injuries.

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

Security system with the brain as a model

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