MIPS— Multi-Directional Impact Protection System can provide more protection in certain impacts. The main components of a MIPS-equipped helmet are 1. The Interior Foam Liner, 2. The Low-Friction Liner, and 3. an elastomeric attachment system. In an angled impact, the elastomeric attachment system stretches to allow the foam liner to rotate independently around your head. Hard Shell construction produces great helmets at a great value. A rugged outer shell is moulded and then attached to the EPS foam liner. Thermostat Control adjustable venting allows you to custom-tune airflow instantly with a simple, low-profile control button on the outside of the helmet Our Stack Vent was developed based on research showing the majority of warm air that can cause fogging comes from the goggle's centre top vent. Aligning the Stack Vent in the helmet with the centre vent of the goggle helps keep it clear and fog-free. The In Form Fit System makes it easy to dial in a custom fit in seconds — even with gloves on. An ergo-friendly dial at the base of the helmet provides up to 6cm of adjustment and enhanced stability.
