Quality from a surprising source

How long has it been since Kmart was around here? I just looked at the label in one of my favorite non-Bean tee-shirts and found that it was by Route 66 and that Route 66 is a Kmart house brand. The short sleeves are not too short, the neck has never stretched, and, despite being worn in the sun and washed hundreds of times, it shows no wear and has never faded but is still black. An on-line search linked the brand with Kmart but unfortunately crew-neck shirts are not shown.
