Fast, Fun, Flowline

Replacing the ever-popular A2 helmet within the Troy Lee Designs half-shell helmet lineup, the Flowline SE brings high-performance features, modern styling, and exceptional protection to trail riders looking to up their game. The Flowline SE is an upgrade from the Flowline, featuring a dual-density EPS core to strike the perfect balance between impact absorption and weight—while also including a FidLock magnetic buckle and an antimicrobial inner liner. This Virginia Tech 5-Star-rated helmet has extended rear coverage to better protect the back of the head, with an integrated MIPS® system to reduce the rotational forces from certain types of impacts. When the going gets hot, and the effort ticks up, the 14 massive vents direct airflow over the head, helping you keep your cool while keeping you protected.



  • Dual-density EPS core offers a high level of protection at a reduced weight
  • Full wrap in-mold construction with the right amount of rear coverage to protect without adding bulk
  • FidLock magnetic buckle for easy closure, even while wearing gloves
  • MIPS® rotational impact brain protection system provides additional protection from rotational forces during certain types of impacts
  • Virginia Tech 5-Star Helmet Rating their highest rating for helmet safety
  • 14 massive high-flow ventilation ports increase airflow through the helmet at any speed
  • Antimicrobial inner liner to keep the stink out after repeated rides
  • 2-way adjustable visor lets you adjust the coverage you need when you need it
