The ergonomic, three-dimensional pre-forming of the cheek pads ensures that the helmet rests extensively on the cheek and thus provides a stable fit even at higher speeds. A tight but comfortable fit on the cheek and chin arch also reduces drafts and contributes significantly to noise reduction.
If the inner padding of the helmet is worn out after a long period of use and many kilometres, or if it can no longer be cleaned, a replacement will restore the original fit and ensure a fresh, hygienic helmet interior.
