I use the shorts for the sport. They fit very well, and also have an internal network. Unfortunately, you realize very strongly that the trousers are made of synthetic material. This means, for example, also, that the pants already do again sport a strong odor. Have they also attracted twice times (between well aired), and thereafter the smell was unbearable. Smells somehow to rubber, but the smell is only triggered by contact with sweat. You have the pants so really after every time wash do sports. Property me now ordered a cotton trousers.
