Bought these to put over ordinary jeans, found that the straps were a bit short and had to be done up very tightly for use on a motorbike. I have used them as elbow protectors under a jacket and they work fine for that task. However, my main use for them is a knee protectors when kneelng on hard surfaces, for that they are great. If you are looking at good, cheap knee protectors for work these do the job well.
