It could be the soap Heather...maybe I'll try just rinsing in cold water a few times. The shirt generally feels comfortable and is not rubbing. It just gets itchy all over. I was a little red and irritated after a hard two day in the desert. But it cleared up after a shower. I have shirts that are 50/50 cotton/polyester and no problem. This is the first time I have moved over to this combination of materials.

Interestingly, looking on line others (albeit only a few) have had similar problems. Just the itchiness. I have to admit to spending most of my life in cotton or wool (next to my body).
