Product Description - Lightweight protection on the road bike Take your road performance to the next level with the Aries MIPS Spherical helmet from Giro. This ultra-light road bike helmet features the MIPS Spherical safety system integrated into the helmet shell. The hard outer shell is extended fully under the EPS helmet shell to prevent damage from kicked-up rocks. Thanks to the integrated AURA reinforcement arch, the 24 wind tunnel ventilation openings are maximally large, ensuring a comfortable head climate even on hot, demanding days on the bike. The helmet pads are equipped with Ionic+ technology to keep them hygienically fresh. Woven-in silver threads provide an antibacterial effect, preventing the development of unpleasant odours. Slim straps and a delicate, easy-to-open buckle contribute to the Aries' sporty performance, while the Roc-Loc 5 size adjustment system allows for easy customisation to your head circumference and forehead height.

It also facilitates the shaping of vents, meaning that In-Mold designs typically have better ventilation systems and a lighter weight. Ionic+ Ionic+ padding has an antibacterial effect and prevents odour build-up, thanks to woven-in silver threads. Additionally, the pads dry quickly, cool in heat, and warm in cold. MIPS Spherical MIPS Spherical is the further development of the "Multi Directional Impact Protection System," a protection system for bicycle helmets. It features not one, but two movable protective layers. These can move in all directions, functioning similarly to a joint. This protects the brain against angular impact. The principle of the brain's natural low-friction layer is adapted to minimise the forces that occur. Roc Loc 5 The size adjustment mechanism is encased in a small housing. It can be adjusted in small increments with just two fingers. It also allows for height adjustment in three incremental levels. Wind Tunnel Ventilation Internal ventilation channels and vents direct cool air around the head and expel excess heat.
