So banana republic sell same product and when I wear that I feel lot comfortable and breathable. This one is suffocating and feels like my skin is sweating. I mean USA everywhere you go almost have AC so only time we need cold layering when we are out and we can easily wear jackets. So why not they make it breathable like Banana Republic makes. Same fabric same cotton same buttons. Just matter of good weaving and adding some material if like spandex or something which can make it lot better comfortable. So don't buy if you want to sweat and have armpit smelling after 2 hrs of wearing this.
