I purchased the xl navy blue and black athletic skirt with no stripes. The skirt is of good quality material. I have purchased these in the past as well. The 3x does have a thicker material then the xl so I'm not sure if they will last as good as the 3x material. My 3x skirts I have swam, kayaked, hiked and wear them pretty much everyday and they have not had any pilings or tears. I absolutely love these athletic skirts.
