The smell will come later. I'd recommend washing the shirt after a day to remove the bad smell. The 10 min is in the full sun while exercising. Sitting behind a desk in a closed environment I'm able to wear it for ±1-2 hours with effective cooling. If the shirt is dripping water, it's too wet and you should press out the water more. Also a thicker cotton feels less comfortable in my opinion, I prefer to wear a thin one and wetten it more frequently!
