The POC OBEX SPIN helmet provides protection for various skiing and snowboarding styles. It is made from an EPS padding, PC shell, and an ABS outer shell. Lightweight, it is perfect for all day use. The inner size adjustment system allows you to adjust it for a perfect fit. The cover vents allow the user to open or close the helmet ventilation for maximum comfort in all weather conditions. The integrated air vents on the front of the helmet allow air to escape from the goggles, thus preventing fogging.
