Notice in the wintertime months my crew was wearing under armor  shirts under their spray wash uniform T-shirts. I realize that SH was not affecting these shirts. Just did a trial run Of some poly/spandex blend shirts , Andoff brand of "under armor". They are very cool, moisture wicking and seem to be durable. Wore the black ones on a job yesterday spraying at 2% and noticed no problems with color fade at all. They look just as good at the end of a 10 hour shift as they did in the morning when we put them on, The black hides all the dirt! Our final price was $14.40 each.
