Rail Race redefines our iconic Rail sunglasses as a limited edition 2-lens interchange model. Still equipped for any trail, Rail Race has added lens vents and laser etching around the rimless lens design. With its rimless shield frame, Rail Race offers top-notch protection for your eyes from UV rays and debris while still allowing you maximum airflow. Whether racing on a bike path or pedaling through pine forests, Rail Race will keep things cool and comfortable!
