No it's not traditional dri fit. It is 60/40 cotton polyester blend. It is loose fitting as well. I usually wear a large in jordan t's, went with a Medium on this one and it's perfect. I own 4 of them now.
The Jordan Jumpman Dri-Fit T-Shirt - Men's measurements are (Length/Chest-Arm pit to Arm pit): M=28"/20", L=29"/22" and XL=30"/24". The Nike Pro Combat Core Fitted S/S Crew is going to have more of a compression fit than the Jumpman Dri-Fit Shirt.
