Worthless!
I wore and washed these three or four times before they developed a rip between the crotch and thigh which I noticed the last time I took them out of the washing machine. Worst long underwear bottoms I have ever purchased, didn't even last a month. Also they can be very tight and difficult to get on, just getting my feet through was often a struggle though once on they seemed to fit alright. Last time I'll buy these.
