Today I have the sports underwear with - worn 10 degrees Celsius during the Nordic Walking and can only say one thing: SUPER !!!! The set really delivers what the manufacturer promises. It adapts easily to the movements, the cold makes outside and draws sweat away from the body. So I will wear them at these temperatures with joy and soon try the cross-country skiing as well. That some customers of languages that the set would be an unpleasant smell, I can not confirm. I have washed of course before the first day and it smells normal. Whoever designed for sports is looking for a suitable underwear, which I would highly recommend this set highly enough; in the truest sense of the word ....
