Named after the gateway to Utah's Uinta Mountains, the Eastern Outer Kamas Photochromic Mountain Bike Sunglasses were built for riders who chase early morning climbs and late-night descents where the light never stays the same. The light-adaptive photochromic lens shifts automatically from bright sun to low light — so you stay locked in no matter what the trail throws at you.

A TR90 frame keeps things durable, flexible, and featherlight at just 32g, while the wide wrap-around fit blocks wind and debris on every descent.

Details:

  • Frame: TR90 — durable, flexible, and lightweight; 145mm wide × 58mm height
  • Lens: Light-adaptive photochromic — 100% UV400 protection
  • VLT Light Range: 28% (bright sun) ↔ 91% (low light) — adapts automatically to UV conditions
  • Weight: 32.1g (1.13 oz) — ultralight for all-day trail riding
  • Free U.S. Shipping: Arrives in 3–5 days
