Query: Suspected Fake if Bought from Dealer: FogDog

I know this is a product review, but I need to bring up that I have bought over 20 pairs of these Under Armour Heatgear Compression shorts in the past, but if bought from this company, I suspect they may be fake. The material in the shorts as well as the band are rougher and seem of a lower grade material then what I've bought directly from "Under Armour". Two of my three pairs bought here have had the bands separate from the shorts with normal washing/wearing over a 2 month period. For reference, the oldest pair I have from "Under Armour" has lasted over 3 years with normal washing/wearing!!!
