The Merino Active thermal underwear is made from high quality Merino wool from New Zealand. 100% Merino wool made from the finest long fiber will hug, warm and work great for sporting activities. The material is comfortable on the body, naturally absorbs and wicks away moisture, and keeps you warm even when wet. Functional underwear made of wool is naturally odour resistant even when worn for long periods of time and has excellent thermoregulating properties. This functional shirt features a looser, more civilian fit and a high-quality print. SENSOR MERINO WOOL from Sensor Activewear on Vimeo.
