The Troy Lee Designs Flowline SE Helmet is a top-tier choice for mountain bikers seeking a perfect blend of protection, comfort, and style. Engineered specifically for MTB trail riding, enduro, and bike park adventures, this helmet incorporates the latest safety technologies while maintaining a sleek, minimalist aesthetic that embodies the Troy Lee Designs brand. Its lightweight construction ensures you stay agile and comfortable, even on the most demanding trails.
Equipped with MIPS® technology, the Flowline SE Helmet offers enhanced protection by reducing rotational impact forces, a crucial feature for off-road cycling. The dual-density EPS foam combined with full-wrap in-mould construction delivers superior absorption against both high and low-speed impacts, while the extended rear coverage adds an extra layer of defense for your head. With 14 strategically placed vents, this helmet excels at airflow management, keeping you cool and dry throughout your ride.
Designed for precision fit and convenience, the helmet features the TLD precision fit system with three adjustable height settings, allowing you to customize the fit to your preference. The Fidlock magnetic buckle enables easy one-handed fastening, adding to the user-friendly design. Additionally, the three-position adjustable screwless visor lets you tailor your protection against sun and debris without hassle. The soft antimicrobial comfort liner reduces odor, ensuring you stay fresh mile after mile.
