Great fabric. Perfect for the summer cycling and running I have planned. The extra plus is how reflective the material seems. You can be spotted a mile away. And because of that, its a good thing it looks stylish as well. My one concern for other buyers is purchase a size up. I normally wear medium t-shirts, and being 5'10'' and 145 pounds, I would never think of fitting into a large, but it is a must for this singlet if you like breathing. Overall, great product.
