I was skeptical for a bit and kept their website open in a tab for a good couple of weeks. I finally decided to do it and I am so glad I did. The shirt does not get wet. I will go the whole day in 90-100 degree temps and my face and my legs are the only parts of my body that realized that I even sweated at all. The shirt absorbs it immediately, and it doesn't feel all chemically manipulated like some other shirts out there. It stretches great yet not too much and not too thin and when your skin sweats the fabric still glides when you move and doesn't get caught up like other poly shirts do. Buy it.
