Consider 100% linen or a blend as well for hot summer days. I have a few short-sleeve linen shirts which are great for days over 28°C. Linen has a coarser weave than cotton, and breathes even better. It can handle sweat better too (dries faster when wearing). I don't have a dryer, so all my clothes are hung to dry. Jeans tend to go in the seat first. I think I average eight years or so, wearing jeans most of the year.
