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 molded and then attached to the EPS foam liner. 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.
