The all-new Giro Insurgent Spherical offers the protection that top riders demand, from the Enduro World Series to the Red Bull Rampage. Giro's engineers have maximised the inlets for cool, fresh air, optimised the outlets and connected everything with deep air channels. A lightweight, soft and absorbent pad set includes a forehead pad with a special shape that draws sweat away from the eyes. Two different cheek pads are included for each of the three sizes, allowing you to customise the helmet and remove them quickly and easily in the event of a fall thanks to the push-button system. At 1,040 grams in size M/L, the Insurgent is very light, although it has additional safety via the efficient Spherical Technology. The Insurgent Spherical uses two inner helmet shells that work like a ball and socket to redirect impact energy during a fall. One shell is made of EPS foam, which is good at absorbing energy in high-speed crashes. The other shell is made of EPP foam with lower density and rebound properties that absorbs energy in low-speed crashes. Other features include a patent-pending flex zone on the lower edge of the helmet that helps prevent collarbone fractures in certain cases, and tool-less breakaway visor screws with integrated hexagonal socket for easy removal and a central visor screw hole that serves as an ideal mount for action cameras. The new Giro Insurgent Spherical is the optimised protection for riders who are redefining what is possible in progressive mountain biking. MIPS SphericalMIPS Spherical is the evolution of the Multi-Directional Impact Protection System. Manufactured in the typical Giro design, the two layers of EPP foam in two degrees of hardness act as a kind of joint that can move a few millimetres in each direction, effectively reducing rotational energy at certain impact angles.
