The Progress TASMAN men's T-shirt with short sleeves is made of a soft, very pleasant to the touch material that combines the best properties of two functional components - merino wool and polyester. Merino wool has excellent thermal properties. It keeps you warm or keeps you cool, depending on your current body temperature. It also prevents bad odours and retains its warming properties even when wet. Polyester helps with moisture management and is quick drying. These features make this shirt wearable all year round. The shirt is sewn with an active stitch, which provides the product with up to four times more flexible seams than normal seams. The loose cut provides comfort during everyday wear and during sport activities.
