Before we went ahead with a MacKenzie & Marr T Shirt we washed and wore and washed and wore and washed (well you get the idea) dozens of T shirts. In the end everyone agreed on a clear winner as the best 100% cotton heavyweight T. The MacKenzie & Marr New Logo T-shirt is a  Gilden Ultra Cotton T. Before you buy one of our T shirts you better make sure you like it because you're going to own it for a long long time!
