^I believe it works for any jeans, although I've only tried it for a pair of rigid TR's and two pairs of R&R's. I was able to permanently shrink my RR Alpha Kiedis, but I think it's because the fabric content makes it easier to shrink. My TR's were good for a couple of wears, but eventually loosened up. Another pair of my R&R's were the 98/2 elastin blend, and these didn't shrink at all. I had to eventually get those altered.
