The Active Warm T-shirt is an excellent basis for layering this winter, so you can concentrate fully on your winter workout. The short-sleeved top is made from breathable, quick-drying polyester material that provides good thermal insulation, wicks away moisture and helps to equalise your temperature during exercise, so that you feel pleasantly warm and dry at all times. Effect by Odlo technology prevents the development of unpleasant odours, flat seams prevent chafing on the skin, the longer cut at the back protects the lower back and the wonderfully soft material ensures a snug, comfortable fit all day long. The "Effect" functional fibre with silver ions incorporated into the material stops bacteria from multiplying and effectively prevents unpleasant odours from forming. "Effect" works without chemicals, is kind to the skin and offers a high level of climate comfort. This fabric is characterised by its good insulating properties thanks to the roughened inside, good moisture transport, short drying time and elastic properties.
