Any facts---or opinions---about tthese non-iron shirts? Formaldehyde (sp?) is used to keep the wrinkles out. I frequently wear shirts with no t-shirts---just never liked 'em. But now I would have these formaldehyde-laced shirts on my chest/back/arms all day. Something tells me that can't be good to be exposed to this this stuff for 10 hours/day over a long period of time. And one can't help but breathe in fumes from these shirts simply because of the proximity to one's face. What say you?
