Review on Adidas Heat Rdy Training Glory Amber Sports & Fitness by John Banks

I bought this t-shirt at my local adidas store in Tysons Corner, Virginia. It was and still is my favorite training shirt. I then ordered two different colors of the same t-shirt from Revain. Both had a stain in front of the shirt after the first hour of normal use, causing the thread to begin to unravel. The first one was replaced but when it happened to the second shirt I thought something must be wrong. . Could these be sale items? Why does the same error appear on two different shirts but in the same place? I prefer to play it safe and just buy my adidas shirts in a shop nearby.
