Men's wool underpants are made of high quality Merino wool from New Zealand. Functional merino wool underpants are very comfortable on the body, and thanks to their fine and long fibres they naturally absorb and wick away moisture, keeping you warm even when wet. Merino functional underwear is odour resistant even when worn for extended periods. Merino has excellent thermoregulatory properties. SENSOR MERINO WOOL from Sensor Activewear on Vimeo.
