I really do like these shirts! Different model differs in the wash load but regardless I would always turn them inside out before throwing it into the wash load. Make sure to select gentle and not normal. Of all the colors...the white shirts are the easiest to be be ruin under normal wash. Overall, the shirts fits and fits me very well. They are extremely comfortable. For hot days the 6410 series that is non-black or white colors attracts too much heat in the sun. I was assuming the black would do worst but it actually outperform the other colors. Still...I wouldn't change my choice. It's either these or target shirt brand which is near equivalent in both quality and comfort.
