Personally for me the wrong material

I wear imm retro shorts, but generally only of cotton, or at least with a high cotton content. These shorts made of microfiber (according to manufacturer 90% polyamide, 10% elastane) were mei first attempt of another material.

First, I have the shorts washed according to instructions (Care instructions: Machine wash warm 40 ° +). This has funktiniert prima, the material has not changed and the size has remained the same (ie, not running). The Passfom the shorts as seen in the figure and as described in the text.

After a day of wearing, I must say allerings that I personally with this material do not come clear on the skin, to me, is rather unpleasant.

Generally, and I want this product to devalue not here, but I personally can not wear shorts made of this material.
