Giro Trig Mips Helmet

INTEGRATED MIPS BRAIN PROTECTION SYSTEM - All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding strict safety standards; Giro helmets equipped with integrated Mips are aimed at reducing rotational forces HARD SHELL CONSTRUCTION: Hard Shell Construction produces great helmets at a great price; a tough outer shell is molded and then attached to the EPS foam liner OPTIMAL COMPATIBILITY - For optimal performance of both helmets and goggles, Giro products are designed to work together, ensuring an optimal interface between the helmet and the goggles for optimal fit and reliable, worry-free operation STACK VENT TECHNOLOGY - Our Stack Vent was developed based on research that showed that most of the hot air that can lead to fogging comes from the goggles' upper center vent; Aligning the helmet vent with the goggles' center vent helps keep them clear and fog-free THERMOSTAT CONTROL: Adjustable ventilation with thermostat control allows you to adjust airflow instantly and customarily with a simple and discreet control button located on the outside of the helmet; no other system is faster or easier to adjust
