The reinvented RPHA 90S is the most compact modular helmet, resembling a full-face helmet through weight and appearance, yet functioning as a modular helmet. The Premium Integrated Matrix (P.I.M. Plus) shell provides enhanced shock-resistant performance and a comfortable and very lightweight helmet using reinforcement materials that include carbon and carbon-glass hybrid fabric. The anti-fog and anti-scratch coated sun-visor has increased visibility to reduce eye strain and block sunlight. To reduce the noise in a modular helmet, the RPHA 90S has a 3D-engineered low-noise interior that is focused to reduce noise significantly. For convenience, the EPS design accommodates eyeglasses and sunglasses and also has recessed areas for custom speaker placement.
