Training in winter requires a baselayer that's both technical and comfortable. Developed to meet these demands, Grid is crafted in the proven Polartec Power Grid for versatile warmth and advanced thermoregulation.
This highly breathable fabric, which relies on its patented grid design for moisture management, dries instantaneously, absorbs sweat vapour and diffuses it to the exterior for fast evaporation. What else? Odour-resistant for a long-lasting performance.
