Sublimation on this is SOLID. True to size. Definitely does not feel like poly nor does it feel like a performance shirt. It doesnt feel soft like people here say. Its hard to explain it but, we are in a triathlon community and, I do wear a lot of performance, dri-fit, and moisture wick apparel suits and Tees and you will notice that real performance wear are very breathable and soft. This seems to trap heat in your body after all ...this is still synthetic. If you want real performance, go with a real performance brand where they really wove fibers differently. But I am getting this for the sole purpose to put my designs on. These are WORTH IT. VERY IMPORTANT ...they shrink !!
