The quality of the materials is very good. Seams feel very strong when pulled on. Feels like a heavyweight cotton t-shirt that will last through many years with fishing trips and harsh washes. Only problem I have with it is that although it is a regular cut t-shirt, it runs a little small so go up one size if you're looking for a slightly looser fit. I'm normally wear a medium but the medium seemed more small to me or an athletic type fit were it hugs your body more.
