Giro Insurgent Spherical Fullface sisak XS/S (51-55cm) matte harbor blue

Gives you confidence and protection

The all-new Giro Insurgent™ Spherical offers the protection Giro's top riders demand, from the Enduro World Series to Red Bull Rampage. Engineers have maximized intakes for cool, fresh air, optimized exhaust vents, and connected it all with deep air ducts. A lightweight, soft and absorbent pad set includes a forehead pad with a special shape that wicks sweat away from the eyes. For each of the three sizes, two different cheek pads are included in the scope of delivery, with which the helmet can be individually adjusted and which can be removed quickly and easily in the event of a fall using the push button system.

At 1,040 grams in size M/L, the Insurgent is very light, although it has additional safety thanks to the efficient Spherical Technology™. The Insurgent Spherical uses two inner helmet shells that work like a ball and socket to redirect impact energy in a fall. A shell is made of EPS foam, which is good at absorbing the energy in high-speed crashes. The other shell is EPP foam with lower density and rebound properties that absorbs the energy in low speed crashes.

Other features include a patent-pending flex zone on the bottom edge of the helmet that helps prevent collarbone fractures in certain cases, tool-less breakaway visor screws with integrated Allen key sockets for easy disassembly, and a central visor screw hole that makes an ideal action camera mount serves. The new Giro Insurgent Spherical is the streamlined protection for riders redefining what's possible in progressive mountain biking.

Technologies used

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

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.
