Airoh Trials Helmet TRR S Keen

The Airoh TRR S Keen Trials Helmet is an ultralight, highly ventilated helmet designed for trials, off-road and mixed road riding. Constructed from Airoh’s HPC (High Performance Composite), the TRR combines a lightweight feel with excellent ventilation and everyday comfort.

Produced in two outer shell sizes for improved fit and proportions across the size range, the TRR S features extensive ventilation to keep air moving around the helmet – ideal for slower, technical trials riding where keeping cool is essential.

A removable and washable hypoallergenic inner lining provides lasting comfort, while the micrometric retention systemmakes the helmet quick and easy to secure and adjust. An integrated anti-theft ring adds extra practicality when you’re away from the bike.

With its distinctive Keen graphic, the TRR S is a versatile choice for riders wanting Airoh’s lightweight composite construction in an open-face trials helmet.
