This is NOT a real Nintendo product as advertised.  I purchased two sizes, one Youth M and one Youth S.  The Youth M is an authentic with a real Nintendo seal and vibrant colors.  This one, size Youth small is far from being authentic.  Colors are faded and the tag is just sewed on top of a cheap shirt that still has it's tags.  What happened?! I have uploaded pictures of both to compare authenticity.  Buyer beware....
