It is light weight and not bad money wise. It does got dual breathing outlet which makes it easy to breath somewhat like in a respirator (gas mask) but I was frustrated to find that it has got standard size with little freedom for me to fit comfortably. The size of the strap is not enough to fit in to all. Infect it is enough for a small or max medium size or average person. For me it just strap to its edge or if I pull the straps to have slight better grip the way it should be providing good seal then my ears are flip forward and mask sits on my nose and mouth as if someone is placing there hands on my mouth. In short what I needed was a bigger size then the one I received but unfortunate it is only available in standard size fit to all.
