Ok. So the pads I have are Oasics Jr. 09 Kneed pads. They are a little tight (I have fat arms) but they are good. Just need to be dyed and the Oasics Demo trimmed off…easy peasy.

(I have the white pair)

*Note that is not where I bought them…that is just a reference as to what they look like

These are the ones I have, that look just about identical to the ones in the movies. Like I said, all you have to do is tuck under the excess fabric and sew it there, which is really easy. And then dye them gray… although they need to soak for quite a long time. I actually think mine need to be dyed again, as they're not dark enough. And like I said, if you're going to order these, you might want to get a smaller size than you would think. I bought large, but you have to remember, they're knee pads so the sizes are for your knees, not your elbows.

So I would probably want to get the Jr. size?

Absolutely not.

These things are tight. My pair of Adult Large knee pads are snug on my arms… and I don't have big arms.

You definitely don't want to go anywhere under Adult Medium, and even that probably isn't the best idea, as you'll start to feel uncomfortable after wearing them for a while.
