In our business, these new age polyester shirts don't mix with us sweating so fast it doesn't have time to evaporate before our pants are soaked twice as much. I see your point on it lasting much longer and being more durable, but cotton has a purpose. As long as I change my shirts out between jobs, cotton is always gonna be my choice. Price isn't a factor in this case. I get the best cotton shirt available, not cheapo wally world shirtsBuy 100% polyester with dri tech. They breath. Ditch the cotton and cotton blends. There cheap for a reason.
