The Ortovox 230 Competition Base Layer Top is made seamless in a circular knitting process to serve every body zone with the right merino thickness during exertion and cold. The basic rib structure with 190 g/m² merino gives the functional shirt elasticity for maximum freedom of movement. A particularly breathable mesh structure is used in heat spots, while the 240 g/m² thick wool provides warmth in cold-sensitive zones such as the kidney area.
