The SCOTT Symbol 2 Plus D has been designed and developed for the All Mountain Freerider who wants to take safety to the next level. With three key safety technologies: D3O® Technology, MIPS® and 360° Pure Sound, you will be safe at all times. Another key focus for SCOTT's engineers was to provide a helmet that performs equally well in extreme cold or warmer conditions. Thanks to their clever dual active ventilation solution, that's achieved. Through innovation, technology and design, Scott were able to develop the safest and most ventilated helmet they've ever created.
