It's designed to be worn under sports jerseys, training tops, or tracksuits, making it a versatile addition to a young athlete's wardrobe for various sports and activities. Care: The base layer is machine washable. To maintain the integrity of the LYCRA® fibre and Optivent technology, always check the specific care label on the garment for detailed instructions.
