Giro Insurgent Spherical Mountain Bike Helmet

Features

• Spherical Technology's Ball-and-Socket design, powered by Mips®, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin.
• Giro engineers designed precise placement and shape of intake vents to optimize cool air flowing over riders’ heads.
• Giro's complex Wind Tunnel venting system allows hot air an easy escape route from the rear of the helmet.
• Tool-free breakaway visor bolts are engineered with an integrated Allen key receiver for easy removal and replacement in case of crash.
• In case of emergency, cheek pads are easily removable without disturbing the riders head & neck position.
• The zone along the lower edge of the helmet is designed to allow some flex, reducing the role a helmet can play in certain collarbone impacts.
• The central visor bolt hole does double duty as an ideal location for mounting POV action cameras.
• This revolutionary fit system adds a new dimension to helmet performance by enhancing cooling, as well as fit comfort and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc® Air DH allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet.
