Review on Pack Essentials Performance Training Breathable Sports & Fitness in Running by Dave Hammon

I bought these on a cheap jersey because there are "sweat stains" on a white jersey which are not actually sweat but the deodorant you are using. Claims say that natural deodorant won't do this, but it does happen over time. As this happens I don't want to spend too much money on t-shirts and the shirt itself works great but after the first run in the washer/dryer they shrink like crazy. I wear XL shirts so I have LT shirts so they don't stand out but I had to make an XL size on these shirts and wash them right away.
