Everything I have seems to be holding up just fine. I usually wash gentle cycle and air dry. I think in all my years buying Nike clothes, the only issues I have are swooshes melting on some of the used clothes I bought from the 2006-2007 lines.
I had the White polo with blue lines on the side (Like Fed's white/green crew from the AO 2006) and the swoosh went crazy. I had dark blue spots all over the place. Somehow it got sticky and transfered its color all over the shirt. A mess! It got thrown out, obviously.
