IMO, the stuff Nike is making this year (at least for Nadal) is bad quality. I've bought some of it and I am really unhappy. I strongly advice anyone to avoid buying the Nike top motion shirt or any shirt with a colored stripe across it. The stripe is poorly made and it starts to crack after wearing the shirt only a few times. I hope that their next season (2010) is much better.
As for the shorts, I do own them and I agree they are very big in the hip area. All in all they're not bad but the Nike Nadal board shorts from 2007 are far better. IMO best shorts Nike has ever made.
