If you need something.
I suggest you go up a size, or two. I ordered a size larger then I normally wear, and they were a little small. Nice waist adjustment on pants, so if they are larger, you can cinch them in. They get pretty hot, they do not breath well, perfect for colder riding. There is not much protection, or grip, on side of knee area. That said, they do work if you don't ask too much of them. Have not hit the ground in them yet, or had them very long, but they are holding up so far.
