2025 Giro Insurgent Spherical Helmet

The Giro Insurgent™ Spherical delivers the protection and comfort that top gravity riders from Rampage to EWS demand, with the ball-and-socket design of Spherical Technology™ paired with best-in-class cooling power.

Confidence to commit

From the Enduro World Series to Red Bull Rampage, top riders demand the Giro Insurgent™ Spherical and the confidence it delivers. Our engineers maximized the intake points for cool, fresh air, resulting in cooling power 50% more efficient than the Disciple™ Mips®. A lightweight, soft-touch, and absorbent pad set includes two different cheek pads with each of the three sizes, allowing for a customizable fit, which are secured via a directional snap system allowing for easy removal in case of a crash. At 1,040 grams in size M/L, the Insurgent is 200 grams lighter than the Disciple Mips despite additional features including the advanced protection performance of Spherical Technology™. Insurgent Spherical utilizes a pair of different density EPP and EPS foam layers that work like a ball and socket to redirect impact energy in a crash. Additional features include a patent-pending Flex Gasket along the lower edge of the helmet, designed to reduce the role a helmet can play in certain collarbone impacts, tool-free breakaway visor bolts with integrated Allen key receiver for easy removal, and a central visor bolt hole, which does double-duty as the ideal mount for P.O.V. action cameras.

WHAT IS SPHERICAL TECHNOLOGY?

The unique ball-and-socket design of Spherical Technology utilizes two separate liners to help manage impact forces. The material and density of the inner and outer liners can be optimized with Progressive Layering to help manage a broad range of impact forces: the Insurgent features an outer EPS layer (to address high-speed impacts) and an inner EPP layer (with rebound characteristics designed to handle slower speed falls.) When you combine the benefits of Progressive Layering with the market-leading Mips^® Brain Protection System, which can help redirect rotational energy away from the brain, you get more comprehensive protection.

HOW DOES SPHERICAL TECHNOLOGY WORK?

Developed at the Bell+Giro Dome laboratory in partnership with Mips^®, Spherical Technology’s unique Ball-and-Socket Design redirects impact forces, bringing market-leading design, performance and brain protection together without compromising comfort, ventilation, weight or style.

COOLING POWER

STAY COOL UNDER PRESSURE

We tested with our proprietary Therminator head form to measure helmet cooling efficiency and the results prove that Insurgent sets a new standard for full-face helmets. Despite added features and protection, it has 50% greater colling efficiency than Disciple Mips (cooling measured from 100º starting temperature at with 25 mph wind speed).

Features

DIRECTIONAL SNAP SYSTEM

In case of emergency, cheek pads are easily removable without disturbing the riders 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 POV 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.

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.
