With authentic off-road style and a comfortable fit, this helmet delivers it all for aspiring adventurers. Integrated features including a camera mount and compatibility with the Giant Numen Link taillight make it easy to customize your ride. 

Features

  • Trail specific design. Purpose built for aggressive trail and enduro riding. Rail features a new shape with extended rear coverage. 
  • A total of 18 vents with straight, non tapered walls, designed and positioned for off road performance. The size and shape of the vents helps guide airflow through interior channels to maximize ventilation at low and high speeds for better cooling
  • Cinch Pro Fit system.
  • Integrated magnet mount for  Numen+ link taillight

BRAIN PROTECTION SYSTEM

BRAIN PROTECTION SYSTEM Image

MIPS is a patented brain protection system designed to reduce rotational motion from angled impacts that can cause strain in the brain. MIPS mimics the brain’s own protection system inside the skull by adding a low-friction layer between the head and helmet. A helmet with MIPS can absorb more rotational motion from an angled impact.

MIPS REDUCES STRAIN TO THE BRAIN

MIPS REDUCES STRAIN TO THE BRAIN Image

The MIPS patented Brain Protection System was developed by some of the world’s leading researchers in biomechanics and neuroscience at the Royal Institute of Technology (KTH) and the Karolinska Institute in Sweden.

Strain level images from lab tests where two identical helmets, one with MIPS and one without, tested at the same speed show a clear difference. The more red, the more strain in the brain. A helmet with MIPS reduces the rotational motion transmitted to the brain.

WHAT HAPPENS ON IMPACT?

WHAT HAPPENS ON IMPACT? Image

When the head is subjected to an angled impact, the brain slides along a membrane on the inner surface of the skull, which reduces the rotational motion transmitted to the brain. This dynamic was copied and technically applied to create the MIPS Patented Brain Protection System. It is a low-friction layer between the head and helmet, which in experimental and numerical tests has shown a reduction of rotational motion to the brain.

PROTECTION IN ALL HELMET CATEGORIES

PROTECTION IN ALL HELMET CATEGORIES Image

In a helmet with MIPS Brain Protection System the shell and the liner are separated by a low friction layer. When a helmet with MIPS Brain Protection System is subjected to an angled impact, the low friction layer allows the helmet to slide relative to the head. The MIPS Brain Protection System doesn’t interfere with other properties of helmets, such as design and comfort. Since 1996, research and tests have been performed to compare a helmet with the MIPS Brain Protection System to a conventional helmet. The results showed that it was possible to reduce the rotational motion transmitted to the brain by adding the MIPS Brain Protection System.
