The Troy Lee Designs Flowline SE Helmet brings premium trail protection, comfort, and style to riders seeking confidence on every ride. Designed with input from Troy Lee Designs’ elite athletes, the Flowline SE combines advanced safety features, lightweight construction, and exceptional ventilation to create a helmet that’s equally at home on fast-flowing singletrack, technical descents, and all-day trail adventures.
Built around an in-mold EPS liner and featuring integrated Mips® technology, the Flowline SE is engineered to help reduce rotational forces during certain impacts while maintaining a lightweight, comfortable feel. Large intake and exhaust vents work together with internal airflow channels to maximize ventilation, keeping riders cool and focused when the trail gets demanding.
The helmet’s precision fit system allows for easy adjustment to achieve a secure, personalized fit, while the extended rear coverage provides added protection where riders need it most. A full-wrap shell enhances durability and gives the helmet a premium finish, while the adjustable visor helps shield against sun, mud, and trail debris.
Combining trail-ready performance with Troy Lee Designs’ signature styling, the Flowline SE Helmet delivers dependable protection and lasting comfort for riders of all skill levels.
