COOLING TECHNOLOGY By using hydrophilic and hydrophobic yarns, this base layer holds a bit of moisture next to your body while allowing free airflow through the fabric, thanks to the special open knit. You get evaporative cooling directly on your skin. We recommend using this with our coolest jerseys, like the Climber's or Superleggera, though it will work under any breathable jersey.
