I can't say anything about this mask that has a ton of cloth, but we had people wearing the http://bunnypapr.org http://bunnypapr.org in New York City summer. They did fine. There is a fan blowing 30 to 60 liters per minute through the bag/volume. This is like a cool breeze if you aim it at the skin. In the winter, you have to aim it at the shell and not the skin because you'd freeze otherwise. But, mostly these are worn indoors.
