I was very pleased with this purchase.  As one of the reviewers noted, this was great for my short height (5'1", 106) and gave complete coverage whether I was running or doing cross training/mat work.  I know that some people have issues with the inner lining but this is pretty standard for running shorts.  I have a pair of Adidas shorts that are slightly longer than this and I prefer these instead for working out because they bunch less with more rigorous exercises; Not to mention these are less expensive and wick moisture just as well. X-small fit well for me but the waist elastic is definitely tight so I am not sure whether this would be true for all sizes.  I'm not a fan of spending a lot on exercise gear other than shoes so this was a good deal for me.
