Not so great!

The "tag" on the arm (a small 'R' logo) melted immediately when I put these in the drier on low (as directed)and the sleeves now have this little black stuff on them that looks like melted wax. The shirts I bought were white in color, so this renders them unwearable.Aside from that the shirts were about average. Relatively thin material that looks like it might be good for 'breathing' in a hot climate but not so good if you want something warmer.
