Might last 2 years
"Bought 6 pairs of underwear on sale last year. Now just over a year later the wool has pretty much disappeared from the crotch area leaving just the elastic. Every single one is like this. I'm a fit person and my thighs do not rub together when walking or running. They were always washed inside mesh laundry bags on delicates cycle and air dried. They also have a strange smell to them now that I've never experienced before with any underwear. Very unimpressed for the price of them and will not be buying again. You'd hope they would last more than a year or two at how much they cost."
