Insurgent Spherical Helmet
Please select a size.
- SPHERICAL TECHNOLOGY; POWERED BY MIPS® — 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.
 - OPTIMIZED FRONT INTAKE VENTS — Giro engineers designed precise placement and shape of intake vents to optimize cool air flowing over riders' heads.
 - MAXIMIZED REAR EXHAUST VENTS — Our complex Wind Tunnel venting system allows hot air an easy escape route from the rear of the helmet.
 - BREAKAWAY VISOR BOLTS — Tool-free breakaway visor bolts are engineered with an integrated Allen key receiver for easy removal and replacement in case of crash.
 - DIRECTIONAL SNAP SYSTEM — In case of emergency; cheek pads are easily removable without disturbing the rider's head and neck position.
 - PATENT-PENDING FLEX GASKET — 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.
 - STEALTH CAMERA MOUNT — The central visor bolt hole does double duty as an ideal location for mounting P.O.V. action cameras.
 - ROC LOC® AIR DH FIT SYSTEM — 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. Fit and feel adjustments mimic the Roc Loc 5; allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand.
 - IONIC+® PADDING — Pure Silver is the secret ingredient that gives IONIC+® the power to provide natural; permanent odor protection to keep your helmet feeling fresh.

Bike Helmet Size Guide
How to measure your size – Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide. Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.

FOR HELMETS EQUIPPED WITH MIPS TECHNOLOGY, PLEASE REVIEW THE FOLLOWING WARNING: SOME MIPS® LOW-FRICTION LAYERS, ALONG WITH OTHER PARTS OF A HELMET, MIGHT CAUSE LACERATIONS TO THE WEARER’S HEAD/FACE IN SOME ACCIDENTS. THIS MIGHT OCCUR DUE TO THE HIGH PRESSURE ON THE SCALP FROM THE IMPACT OR AS A BY-PRODUCT OF THE LOW-FRICTION LAYER’S MOVEMENT IN CERTAIN ANGLED IMPACTS TO HELP REDUCE THE ROTATIONAL ENERGIES TO THE HEAD.
