The marketing phrase says cotton is the fabric of our lives.
Or death if you hike in it, according to this href="http://outbounddan.hubpages.com/hub/Why-Cotton-Will-Kill-You" target="_blank">blog post by a man in New York calling himself Outdoor Dan. The time stamp says he wrote it last month. The Washington County Search and Rescue team linked to it on its href="http://www.facebook.com/pages/Washington-County-Sheriff-Search-and-Rescue/301765431254?ref=ts" target="_blank">Facebook page last week.
There have been plenty of people over the years discouraging hikers from wearing cotton. I've never read such warnings with the fervor Outdoor Dan gives.
My advice would be to follow Outdoor Dan's advice, but don't think a synthetic shirt alone will keep you safe on the trail. You still need to pay attention to the weather, hike with a group or at least tell someone where you are going, have food and water, etc.
Yeah, I suppose cotton can kill, but not as surely as a lack of planning and preparation will.
