The POC Omne Air Spin Helmet inspires the will for more. Whether on the morning commute or out for a weekend ride, the Omne Air SPIN pushes you to go further. Optimal liner density and thicker core protection zones provide ideal all-round protection for everyday use, while ventilation channels and a low weight inspired by POC's award-winning road cycling helmets the Octal and the Ventral, deliver optimum comfort and functionality on longer rides. By taking POC's whole-helmet approach to the creation of the Omne Air SPIN, the helmet delivers superior levels of comfort, fit and performance. SPIN (Shearing Pad INside), POC's patent-pending silicone pad technology, also features. SPIN is designed to reduce the effects of an oblique fall by reducing the amount of force transmitted to the head and brain. By using the innovative and unique pad technology, which sit directly against the user's head and can shear in any direction during an oblique impact, SPIN pads allow the helmet to move relative to the head during a fall, reducing the force transmitted to the brain. Practical features include a lightweight size adjustment system that guarantees a personalized fit, and an eye garage for easy and secure storage of eyewear when not in use. 305 grams. SM (50-56cm), MD (54-59cm), or LG (56-61cm).
