LS2 Rear Ventilation Advant X FF901 Spectrum - Efficient air evacuation for your helmet

A well-ventilated helmet, from chin to back, is the promise of constant comfort, even over long distances. With Advant X FF901 Spectrum Rear Ventilation, your helmet gets full air circulation to keep your head cooler and your interior drier, mile after mile.

The Advant X FF901 Spectrum Rear Vent is an official LS2 spare part designed to replace or restore the air outlet located at the rear of the Advant X FF901 helmet in its Spectrum finish. When this vent is broken, missing or simply worn, internal air circulation can be disrupted, leading to a build-up of heat and moisture under the helmet.

This part fits perfectly into the anchoring points provided by LS2 and integrates harmoniously with the FF901's Spectrum design. It extracts warm air from the inside of the helmet to the outside, improving thermal comfort and moisture management, particularly on hot days or long rides. Solid and durable, it is designed to support continuous ventilation in addition to the front air intakes.

Easy to install, this rear ventilation allows you to extend the life of your helmet without compromising comfort or aesthetics.
