Children's functional underwear set Merino Active is made of high quality Merino wool from New Zealand. The Merino wool T-shirt is very comfortable on the body, thanks to its fine and long fibres it naturally absorbs and wicks away moisture and keeps you warm even when wet. The Merino T-shirt is odour resistant even when worn for extended periods. Merino has excellent thermoregulatory properties. SENSOR MERINO WOOL from Sensor Activewear on Vimeo.
