Rimless, ultra-light sport sunglasses designed for cycling, running, and all-day comfort. Available in Clarion Blue Fototec and Crystal Smoke Interchange lenses.

The Tifosi Rail XC delivers all the performance of the original Rail—just in a more compact, lighter, and better-fitting design for athletes with smaller or narrower faces. Whether you're riding, running, or out on the ball field, Rail XC gives you the coverage you need without overwhelming your features.

Ultra-light at just 31 grams, the Rail XC features a rimless shield for wide-open visibility, exceptional airflow, and zero distractions.

Why Athletes Love the Rail XC

Lightweight, Streamlined & Ready for Action

The smaller, rimless shield design keeps things sleek while maintaining full coverage from wind, dust, and debris. Perfect for long days in the saddle, fast gravel rides, or quick transitions between sun and shade.

Engineered for Comfort

Hydrophilic nose pads and ear pieces grip tighter the more you sweat, keeping your glasses locked in place mile after mile. Fully adjustable fit points let you dial in comfort for all-day wear.

Built for Any Light Condition

Rail XC adapts to every environment thanks to two lens systems:

• Clarion Blue Fototec – Light-adjusting lenses that shift seamlessly with changing conditions. Ideal for long rides, early starts, or variable cloud cover. One lens does it all.

• Crystal Smoke – Interchange – Comes with three lenses:

  • Turquoise Blue reflective

  • Amber

  • Clear
    Swap lenses to match the light conditions for maximum clarity and safety.

Both versions offer 100% UVA/UVB protection and crystal-clear optics.
