Troy Lee Designs Flowline MTB Helmet

The Flowline is a youth-specific model. It is engineered with a fit profile and shell geometry tailored to the head shapes and proportions of younger riders, rather than just being a shrunken-down adult helmet.

Mips B-Series is a rotational impact protection system. In the event of an angled impact, it allows the helmet to slide slightly relative to the head, which helps reduce the rotational forces transmitted to the brain.

The visor features a three-way adjustable screwless design. You can easily shift it up or down by hand to accommodate goggles or changing light conditions without needing any tools.

Yes, the helmet is built with 14 integrated vents designed to channel airflow across the scalp. This ventilation system is effective at pulling heat away from the head during high-exertion trail riding.

The 360-degree fit system uses a dial mechanism that tightens the cradle around the entire circumference of the head. This provides a more secure, uniform fit that prevents the helmet from rocking or shifting while riding on technical terrain.

Yes, the Flowline has earned a 5-star safety rating from Virginia Tech, which is an independent testing facility widely respected for its rigorous helmet impact assessments.
