Have now taken on a week-long bike ride over 850 km of each day the biker underpants, and the part has passed the endurance test very well. Bin 1.72 meters tall and the size M fit me very well, only the elastic band I was too tight, ie at the end of the day you had bruises on the stomach. The pad is pretty thick and solid, what I find best in the Po area, because then you sit as on a pillow. In the front area I would have liked a more flexible pad, which would then be better adapted to the contours. On the other hand, will cost the trousers only a fraction of what I have so far spent on bicycle pants. Conclusion: I would buy again.
