Ugh, that's SO frustrating when the 'green' option isn't what it seems. I've seen this with recycled polyester fleeces, they SHED like crazy in the wash. All those tiny fibers end up in rivers and oceans, which is a HUGE problem. It makes you wonder if natural fibers like organic cotton or hemp are better, but even they have their own issues. The whole industry needs to get more transparent about what 'eco-friendly' really means.
