Have the protectors appointed and was only a little skeptical at this low price! Were as always delivered very quickly! ... And I have to say I am thrilled - for this price are very stable protectors sitting super. Practically, I also think that there are only two Velcro fasteners on the calves, characterized the parts do not tweak and since I bought them for's motorcycle and thus under the jeans (but already should have a certain length at the knees) wear, fit the kneepads then of himself to. Who is looking for good and cheap knee protectors, is served really well with these parts!
