Extensive wind tunnel testing reveals that the Synthe is nearly as efficient as the fastest time trial helmets. But the Synthe’s greatest attributes are comfort and ventilation. At it’s heart you’ll find Giro’s Roc Loc Air fit system. Micro adjustments allow you to custom tune tension and fore-aft tilt with one hand.
- Roc Loc Air fit system: enhances comfort and stability while adding a new dimension to ventilation and cooling.
- Wind tunnel ventilation: Giro helmets are developed utilizing proprietary Wind Tunnel ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the riders head-while forcing heat and stale air out.
- X-static padding: In addition to being very comfortable, our X-Static pads provide anti-microbial properties to help keep your helmet fresher, longer.
