This is ideal for people who run early in the morning on sunny days with temperatures between 40 and 50 degrees. This shirt is not for a guy like me with a beer belly who goes fishing in Florida when it's 90 degrees. A sweatshirt shouldn't be called a sun shirt, maybe it's a sun shirt or something. Plus it's warmer than a 90 degree sun shirt should be. Slender boys and girls walking around will love it, I think fishing beer lovers prefer the Huk.
