The pants fit pretty good at 187cm and waist and nearly 34 well-trained legs in XL. The Windstopper is beginning to adequately addition to the normal and elastic material processed through the knee and connected all over with this, itself but hardly stretchable. The small zipped pocket at the back served its purpose, it fits into a key. For me, the pants are ideal for temperatures between 5-10 ° C.
After a few (30 ° mechanical) washes unfortunately starts the Windstopper to detach from the rest of the material and begins to bubble. Meanwhile, after maybe 10 washes, the Windstopper is almost completely detached and appears to have also expanded, so that the bubbles are present even in the tightened state. The function is still given, but that now looks really modest. I've never experienced with any similar material. I can only strongly recommend hand wash when these pants will last longer.
After obviously not so rapid wear comes through the Wash at other brands, I give three stars.
