The quality of this top layer is great it stretches pretty well, I’m more muscular type of guy so wearing a medium is typically a tight fit but this has plenty of room to feel comfortable. Breathes well and design looks way better in person. Highly recommended getting a quarter zip from Bad Birdie. Plus shipping was really fast
