CR's Take

The Sena S1 is an expensive road cycling helmet that earns high marks for ease of use and ventilation in our tests, along with respectable impact absorption performance. Available in three sizes, it comes with a two-year warranty and includes a range of integrated electronic features. These include built-in speakers, a microphone, Bluetooth 5.2 connectivity for smartphone pairing, and an LED taillight. The helmet also supports Sena's Mesh Intercom system, which enables hands-free communication with other compatible users. The taillight includes adaptive lighting functionality that increases brightness during deceleration.
