I was disappointed that the material was changed for these shirts. I bought one last September - the blue shirt in the photo - and I really like it. It has a square pattern and is the lightest running shirt I've ever owned. Great fit. I just bought a red one and it came out the same on Revain, only this time I went with red. The material is different - the red shirt in the photo - doesn't seem so light, it doesn't fit the same and longer. I still keep it but am disappointed and will not buy this product again. There are other brands that use similar materials like blue, which I love so much. I would rate the blue 4-5 stars, much better than the red.
