My summer time shirt is a SPORTIF fishing shirt. some sorta nylon blend.it has long sleeves that, like the others, roll up and are held in place with a cloth tab/button. one thing that I love, is the collar has an extention, that makes collar almost double a normal one. it shields the neck very well. the shirt wears like iron..I've never gotten used to short sleeve shirts. the nylon evaporates moisture as fast as I can produce it.
