A summer-weight sock with hi-vis detailing for late training rides and twilight criteriums. Summer cycling isn't a strictly daytime activity. Some days start well before the sun rises; others end after it's set. This sock combines our lightweight summer breathability and cooling with a photoluminescent strip for low-light visibility. A lightweight Lycra blend delivers light compression and generous moisture management. STL (or Spot The Light) incorporates photoluminescent threads to add light to your pedal stroke in low-light conditions. The seamless, 160-needle construction creates a soft, lightweight sheath of frictionless comfort.
