The Progress MERINO FREEBEANIE functional cap is made of high-quality merino wool. Merino is a pleasant and warm natural material that ensures natural absorption and removal of moisture from the skin thanks to the fine and long fibres of the yarn. It has excellent thermoregulatory properties, prevents the feeling of humidity and is characterised by high resistance to odours even when worn for a long time. Merino contains lanolin which has permanent antibacterial properties.
