Product Description The - Lightweight protection on the road bike Take your road performance to the next level with the Aries MIPS Spherical helmet from Giro. The road bike helmet is ultra-light and equipped with the MIPS Spherical safety system in the helmet shell. The hard outer shell is pulled all the way 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 and create a pleasant head climate, even on hot, demanding days on the bike. They are equipped with Ionic+ technology to keep the helmet pads hygienically fresh. The woven-in silver threads have an antibacterial effect and prevent the development of unpleasant odours. Slim straps and a delicate, easy-open buckle add to the sporty performance of the Aries, which you can easily adjust to your head circumference and forehead height with the Roc-Loc 5 size adjustment system.

It also makes it easier to shape vents, which means 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, plus silver threads are woven in. In addition, the pads dry quickly, cool in the heat and warm up in the cold. MIPS Spherical MIPS Spherical is the further development of the "Multi Directional Impact Protection System", i.e. a protection system for bicycle helmets. It has not one, but two movable protective layers. These can move in all directions and function similarly to a joint. The brain is thus protected against angular impact. The principle of the natural low-friction layer of the brain is adapted in order 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 only 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.
