I got two pairs of Bleulab jeans in the mail from Amazon yesterday. Neither are the waxed kind, just the regular.

I'll admit I wasn't totally sure what size to order, I went with a 26. Which fit, but a little too snug for what I would want for traveling. I exchanged for a 27 and they will be here tomorrow.
As for the jeans, I really like the product. I was afraid they might be thinner like leggings, but they are pretty thick, like regular jeans. The reversible features are pretty cool.
And this pair:

Now this pair was extremely small, although the same size and seemingly same style. I returned them.
Given Amazon's great return policy, I just advise to try a few pairs and see which work. But they are pretty neat. I didn't wear them long, but I think the stretch will hold pretty well as anything else.
