About 35 years ago, I bought some t-shirts from Patagonia. The colors, as well as the size and fit, were terrific! I probably got a dozen of them. A few years after I started wearing them, it was discovered that the cotton they were made from was not sustainable. So they stopped making them with that fiber, and in those shapes and colors.
The funny thing is, while that cotton has not been used anymore, those shirts have washed well, even with really tough stains, and they still are in rotation in my wardrobe.
