My 3 1/2 yr. old son is now crazy about Spiderman.  When I saw this, I knew I had to get it for him.  I remember Underoos from when I was a kid and that was over 30 years ago.  The quality seems good and not too much shrinkage.  My son has worn this over and over since he got it and after repeated washings the colors are still nice and bright.  I would definitely buy Underoos again.
