Troy Lee Designs Flowline Helmet

The Flowline is specifically built for trail riding. It balances the coverage needed for mountain biking with a streamlined, understated aesthetic that works well for everything from casual trail sessions to more technical singletrack.

The helmet uses the Mips B-Series rotational impact protection system. This technology is designed to reduce the rotational forces transmitted to your brain during an angled impact, which is a common cause of concussion in mountain bike crashes.

Yes, the helmet features a 3-way adjustable screwless visor. You can easily move it up or down to accommodate goggles or to change your field of vision depending on the trail conditions.

It is designed with 14 strategically placed vents to maximize airflow and keep you cool. Combined with the full 360-degree fit retention system, it provides a stable, breathable fit that stays comfortable even on longer, high-exertion rides.

The 360-degree retention system is highly customizable. It includes a 3-way rear height adjustment, allowing you to fine-tune the fit around the back of your head to ensure the helmet stays secure without creating pressure points.

The Flowline has earned a Four-Star safety rating from Virginia Tech, an independent testing facility that evaluates helmet performance based on real-world crash scenarios.
