I got a pair on ebay, second hand, ages ago. They're a bit baggy now, but the stretch fabric is very hardwearing. The white threads actually seem to be failing before the blue threads. They've never been that good a fit on me. Probably more a woman's fit, but they've kind of worn in to me in spite of numerous washes and I can trade them in if I buy some new nudies from a shop, so arguably they won't have cost me anything, sort of.
