"I tested the Svitoni® socks and thermal underwear made of Prolen® yarn in winter as well as summer periods and I am very satisfied. The SPORT TREK socks, which are made of a very comfortable material, felt really good and seem like new even after frequent wearing. I wear thermal underwear made of Prolen® to almost every training session- it is great for cycling, skating, skiing and cross-country skiing."
