I have one of these and they are very good. It protected me well on Fraser Island against Mosi and Marsh flies. but I wore it in the single skin hammock I was using at the time and when I got home you can see on my back where the mosi had bitten through the hammock and the side net of the shirt. The area that was covered by the cotton material they did not get through. But like all clothes in hot weather it will be hot no matter what you do. I wore it on its own with no t shirt under it and the wind was welcome through the net areas and yes your vision is restricted by the hood but you got used to it.
