Giro Coallition Spherical Mtb Helmet

The lightweight Giro Coalition™ Spherical combines Spherical Technology™ powered by Mips® and Progressive Layering featuring both EPP and EPS foam, with best-in-class ventilation and the added protection of our innovative Halo System chinbar.Only Giro could design an impressively lightweight full-face helmet that still provides heavyweight protection. Just 800 grams in M/L, this NTA-certified MTB helmet still packs the punch of Spherical Technology™ powered by Mips® while Progressive Layering with EPP and EPS foam optimizes management of both high-speed and low-speed impacts. Coalition Spherical delivers best-in-class cooling power by pairing massive front intake ports with efficient rear exhaust vents via deep internal channeling. Coalition´s most impressive innovation lies hidden inside: the patent-pending Halo System combines a chinbar with Pebax® (a material that is engineered to provide the perfect range of flex and rigidity) and elastomeric bushings that are integrated into the EPS to absorb and dissipate kinetic forces. The result is a helmet that exceeds standard chinbar deflection certification testing by almost 2x. Comfort is maximized with the DryCore™ sweat management brow pad, IONIC+™ treatments to control odor, and two sets of removable cheek pads to help fine-tune fit. The Coalition Spherical sets a new benchmark for lightweight full-face protection.Specifications:- Construction: In-Mold polycarbonate shell with EPS liner- Ventilation: 23 vents with deep internal channeling- Fit System: Comfort Liner/Neck Roll/25mm & 30mm cheek pads- Product Weight: 800g (size Medium CPSC)Certification:- NTA- ASTM-1952-DH- ASTM-2032-BMX- EU: CE EN1078- AS/NZSTechnology:Halo System Chinbar:- The Halo System combines a chinbar with Pebax® (a material that is engineered to provide the perfect range of flex and rigidity) and elastomeric bushings that are integrated into the EPS to absorb and dissipate kinetic forces.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.Directional snap system:- In case of emergency, cheek pads are easily removable without disturbing the riders head and neck position.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.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:
