Bell Full-9 Fusion MIPS Fullface helmet XL (59-61cm) mat black/white fasthouse

Based on their legendary Full-9, Bell has developed a full-face helmet that makes no compromises and is perfect for riders who demand everything from their material. Equipped with a high quality fiberglass shell, a wide field of vision, overbrow ventilation inlet ports, padded inner lining and MIPS® technology, this helmet delivers world-class quality and fit. It doesn't matter if you're fighting the clock downhill or flying over big gaps in the bike park, the Full-9 Fusion MIPS® is just the right helmet for you.

Overbrow Ventilation™
Deep air inlets above the forehead bring cooling air into the helmet, which is guided around the head through a matrix of air channels and ensures a cool helmet climate throughout

Velocity Flow Ventilation™
The Velocity Flow Ventilation™ lets the air flow around the head through a sophisticated air channel system and discharges it at the back of the helmet.

XT2® pads
The X-Static XT2® pads are woven with silver threads. Fast-drying and antibacterial, they work against odors. In addition, the X-Static® pads give the driver a cooling feeling when it is hot and a warming feeling when it is cold thanks to their thermal properties.

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.
