Look, we know you can't wear t-shirts every day. Sometimes you gotta button it up, so we're making it easy on you. The open-weave Toad&Co Men's Salton Short Sleeve Shirt is a great lightweight summer short sleeve button-down. The loose weave slub is breathable and soft, and it will only get softer over time (while still holding its shape). It's versatile enough that it might even encroach on your casual wardrobe and replace one of your t-shirts.
