This is a Majestic Boston Red Sox road men's authentic jersey with sleeve patches, size 44/large. This jersey is made with the smooth polyester, not the Cool Base. The front logo and sleeve patches are sewn on. This jersey has some light colored marks on the right sleeve (possibly from being in the heat press when the sleeve patches were being sewn on), see inset photo. Other than that, this jersey is fine. Great deal on an authentic jersey!
