As someone who has worn the bowling shirt from the early aughts, the blue one with the flag stripe that was recently retired, and the newest shirt as an employee in different weather conditions, I can say that I prefer the newest one. It breathes really well, as the material reminds me of Under Armor golf shirt. It's stretchy and light. The previous one was not as bad, but way too thick in the summer, and the old bowling shirts....once you sweat in that thing or got it wet, that was how it was gonna be the rest of the day.
