The material itself is much thinner than it looks in the picture, it looks like a thick t-shirt material. I bought them for outdoor fitness workouts but they would be too thin for anything under 60 degrees Fahrenheit. In terms of fit, it's slim fit and sized, but a bit tight. It just line dries, I suppose if you tumble dry it will shrink. I'm 5ft 8in, 150lbs and I'm pretty tight.
