Actually, MNS this is the first anything with spandex in it. That includes the 80's btw. I will wear the thing only a few days before I wash or rinse it out. During desert outings, I automatically go into water conservation mode and will not waste water rinsing anything I don't have too out. On the overniter I decided to push through and wear it the whole time thinking that this might just be in my head.

It does what it is supposed to do quite well. So I am hesitant to give up on it yet even though one of my thoughts was minor allergic reaction. I think it may be back to cotton in the desert though...
