Troy Lee Designs Flowline MIPS MTB Helmet - Grey

MIPS is the Multi-directional Impact Protection System, a low-friction layer inside the helmet designed to reduce rotational motion transferred to the brain during an impact.

Yes, the visor is designed to be removable for riders who prefer a more open-face look or find it unnecessary for their terrain.

You should replace your helmet if it has sustained an impact, or every 3 to 5 years even without obvious damage due to material degradation.

The interior design is generally compatible with most standard riding glasses; adjust the cradle height if you experience interference.

Measure the circumference of your head at the widest point, about an inch above your eyebrows, and compare it to the size chart provided by the manufacturer.

Adjust the 3-height setting on the rear cradle and tighten the tension dial at the base of the skull.

Ensure the screwless mount is fully seated; push firmly into the slots until a click is felt.

Check that the velcro tabs are clean of debris and press them firmly against the inner shell.
