Organic clothing will burn whereas synthetic will melt. And while catching on fire doesn’t sound like the best of situations, I can assure you that it’s better than having something melt into your skin. It actually takes a lot longer for cotton to catch on fire whereas synthetic clothing will almost instantaneously melt. Don’t trust me? Try burning your shirt with a lighter. Of course, fire retardant materials like Nomex are even better but for someone who doesn’t work with fire much and who isn’t in direct contact, the best price/efficiency ratio is to have 100% organic cotton clothing handy.
