      Castelli Flanders Base Layer Sleeveless

      No matter what the temperature, staying comfortable means staying dry—and that's particularly important for your core. A good baselayer that wicks moisture away from the skin and towards the surface is crucial. Castelli’s Flanders Sleeveless is the perfect garment to handle mild to cool weather.

      The Flanders' rib-knit multidenier polyester stretches to conform snugly to your body, but the texture allows for room between the fabric and your skin, increasing comfort. All of the seams utilize four-needle flat-lock stitching, to avoid any potential irritation areas.

      The mock turtleneck gives you a little extra warmth where you need it, while the polyester mesh armpits allow for airflow. And by forgoing the sleeves, the Flanders Sleeveless can handle days that are a bit warmer than the short sleeve version. The Flanders Short Sleeve's longer back stays tucked into your shorts to keep you covered when down in an aggressive cycling position.

      Castelli rates the Flanders Sleeveless base layer for temperatures between 53.6° and 71.6° Fahrenheit (12°-22°C). It also works great under other baselayers.

      The Castelli Flanders Sleeveless Base Layer is a sensational customer favorite, and we hope you like it just as much.
