I got some Nashbar “C-pants” that I like a lot, the fabric is a nice brushed cordura nylon, the weight of the fabric is just right, and since they are nylon they can get wet without getting uncomfortable. They are cut small, I had to get the XXL, I normally just get L in things (38 waist). They have no stretch, a little would be nice, but it’s not a killer. And right now they are dirt cheap.
I really hope more makers start jumping into knickers, I like them a lot.
