The SEESOFT Air is our extra ventilated CE-level 2 back protector insert that is designed to absorb variable impacts without compromising comfort or freedom of movement. By adding more and larger ventilation holes in the back protector insert, body heat and evaporated perspiration will escape easier than our traditional SEESOFT back protector. Riders can stay cooler and drier when riding in higher temperatures. By applying a multiple-layer concept, REV'IT! has developed a flexible back protector insert that performs consistently in all conditions and after multiple impacts.
