Light, soft, stretchy layer.

My first Brooks product and I'm very happy with it . Very comfortable not overly tight semi-relaxed fit with soft stretchy fabric, awesome stuff. I'm 6'2" 190lb slim athletic build and the medium fits great around the chest and slim around the waist. Also, the heathed pattern looks much better in person.
