Anyone remember Toughskins or any other brands that we used to wear in the 70s and 80s? Have any jeans that you just loved, and hated to grow out of?

I would like to get my hands on some vintage Toughskins, waist size 28-31...I'm sure SOMEWHERE there has to be a bunch of 'dead stock' sitting in a warehouse, basement, etc. If anybody knows, please pass that info on to me.
