Airbrake MTB Troy Lee Designs Signature Goggles. From motocross to enduro to freestyle, dirt track and beyond, Troy Lee Designs® continues to lead the chase pack in innovative color creation and surfacing. Oakley's Troy Lee Collection puts TLD's unique color modeling on sunglass frames that offers changing hues when exposed to variances in shade and sunlight. From enduro to downhill, dust your competition and say goodbye to fogging, heat build-up and debris with the Airbrake MTB goggle. The exclusive Factory Lite Vent mesh is designed to provide increased airflow and ventilation at slower speeds while helping to prevent mud, debris, and rocks from entering the goggle.
