Cotton is a quandary. To me, no fabric is more comfortable, but its environmental impact is vast. Cotton is sprayed with reservoirs of pesticides, dumping tanks of volatile organic compounds onto the soil. The wide spacing necessary to cultivate cottons also diminishes soil fertility. Also, if you use cotton, odds are that you are exploiting a child in Uzbekistan. Is there anyway to avoid culpability?
Synthetics make me feel like I'm wrapped in plastic.
