Giro Manifest Spherical Helmet

The Giro Manifest Spherical Helmet represents the pinnacle of trail-riding protection and comfort. Its innovative Spherical Technology features a ball-and-socket design integrated with Mips® brain protection, enabling the outer shell to rotate independently during impact whilst eliminating hard plastic contact points. This advanced system effectively reduces rotational forces that can cause brain injury. Engineered for superior airflow, the AURA reinforcing arch maintains structural rigidity whilst channelling air through expansive Wind Tunnel vents. The Roc Loc Trail Air fit system delivers precise, tool-free adjustments for a secure, personalised fit, whilst premium XT2 padding with antimicrobial properties manages moisture and enhances all-day comfort. Built for serious riders who demand uncompromising protection and ventilation.

• SPHERICAL TECHNOLOGY — 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.
• PROGRESSIVE LAYERING™ — Giro helmets with Progressive Layering™ use two different density EPS foam liners to address high- and low-speed impacts for more comprehensive energy management
• AURA REINFORCING ARCH — Structural integrity is bolstered by the shatter-resistant and translucent AURA reinforcing arch that runs throughout the helmet.
• INTEGRATED EYEWEAR GRIPPERS — Integrated eyewear grippers help secure sunglasses.
• MIPS® BRAIN PROTECTION SYSTEM — All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Mips-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts.
• ADJUSTABLE MOTO-STYLE SCREW-IN VISOR — This visor features an adjustment mechanism that lets you move the visor up and down in indexed steps. These steps include three riding positions plus a high position for goggle storage above your brow. The design allows you to easily adjust your visor with one hand while riding.
• 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.
• GOGGLE GRIPPER — The integrated rubber goggle gripper on the back of the helmet helps to ensure that goggles stay in place even when you're getting rowdy on the trail.
• ROC LOC® TRAIL AIR FIT SYSTEM — The Roc Loc® Trail Air Fit System offers micro-adjustable fit adjustment; enhanced ventilation; and durable design that resists abrasion; scratches; and UV rays.
• FIDLOCK® MAGNETIC BUCKLE CLOSURE — The pinch-free one-handed Fidlock® magnetic snap helmet buckle combines the advantages of two fastening concepts in a completely new way: Strong magnets make it easy to open and close; while a secure snap functionality ensures a continuous locking force.

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.
