Reading that, and not liking what you bought, it seems like it's the reality of knickers,
is bothersome, but the Idea is OK./
I'm a old post Levi's guy, and found a Jersey Knit fabric gives ,. where a Woven one will not..
pants used in Baseball seem to be a jersey Knit, for freedom of movement.. and sweatpants..
I got some compound fabric track Warmup pants , fuzzy poly fleece on the inside,
smooth nylon on the outside ..
Old and Fat, sweatpants suit me.
