So happy I bought a flo mask pro. It’s very light weight. It’s made of high quality materials, I found both the everyday and pro filters to be very breathable. Once you have it on, you forget you are wearing it. It molds to your face and creates a nice tight seal. When wearing it for long periods of time and in hot conditions, moisture does collect inside. However included is a piece you add in around the inside seal to keep the moisture away from your face. I found even without the piece added, the liquid stayed in the dark grey part of the mask. When I think of how much I have spent on disposable masks and the amount of waste they create, I wish I had bought this sooner. If you are on the fence, take the leap, get yourself a flo mask pro and know you are protecting yourself and those around you.
