Wind Tunel Ventilation: Giro helmets are developed utilizing our 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. This significant increase in air channelling makes a difference that riders will immediately feel and appreciate.
Hardshell Construction: A hard shell helmet is made up of a durable plastic shell that is laminated to an EPS foam liner. They provide performance at a great value.
