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 the helmet shell remains relatively securely on the head in the event of a possible oblique impact. This protects the brain from rotational forces and certain injuries. Click-to-Fit system - for an optimally adjustable fit. FIDLOCK SNAP chin closure. 14 white LEDs at the front and red rear light at the back (rechargeable). Visor and straps with reflective lines. COOLMAX padding.
