First, I want to say, I kept my pants. However, I have criticisms that would no longer be in the price.
The guards can not be used variably. You have a fixed position, if that is too high or too low for its own knees, you're unlucky.
In addition, the existing protectors are only 10mm thick foam pads. They look as if they were cut out of a plate, not preformed. This makes them very uncomfortable, especially on the knees can not take my opinion. But the hip protectors very disturbing.
Finally, the fit.
(I am slim and have the pants bought in the appropriate size)
At the waist, the pants fit like a glove. But the rest of the pants looks for like four sizes too big. On the legs, it is much more cut than what one would expect.
As I said, I keep the pants, but just because I drive without protectors and legs of trousers with leg elastics fasten the boots.
