NikeMen's Long Sleeve Shirt

I have bought 3 of these previously, in various colors, and liked them so much that I wanted the crimson/cardinal one. This was sold by a different vendor for more money, and when it arrived, I noticed it seemed substantially larger than the other 3, despite all being the "same" shirt from Nike in size Medium. (The shoulders matched, but the sleeves were a bit longer and the width and length were several inches larger.) I am pretty surprised that this didn't fit like the others, and disappointed that the seller would sell it as such.
