A large part of the helmet is made from recycled materials: EPS with 20% cork AVID Progressive EPS - a combination of different density EPS ensures that both strong and weak impacts are optimally absorbed. At the same time, the material remains lightweight and provides the best possible ventilation. MIPS B32 - MIPS technology ensures that in the event of a possible oblique impact, the helmet shell remains relatively well on the head. This protects the brain from rotational forces and certain injuries. Click-to-Fit system - for an optimally adjustable fit. FIDLOCK SNAP buckle. 14 white LEDs on the front and red taillight on the back (rechargeable). Visor and straps with reflective lines. COOLMAX padding.
