Where to Buy Rehband?

I’d like to pick up a pair of Rehband knee sleeves, but I don’t know where I can get them. Obviously I can buy them online, but my experience with buying apparel on-line is not so good. When I ordered my first squat suit from inzer I had to send it back four times to find the right size.

I’d like to avoid this, so if anyone knows where I can find Rehband equipment in like a retail store, that would be great. Thanks…
