I have had good luck with Ex Officio with vented sleeves, vented back an de vented sides it's definitely the coolest of cotton shirts. All the vents are held open by Velcro so they really do breathe. The sleeves roll up and are held by Velcro which is nice when you're casting a lot. These shirts are button down and have extra large collars which protect your ne k from being burned. Good luck!
