Review on XAegis Tactical Military Interchangable Paintball by Ray Sheptock

5 stars for intended purpose. make them breathable. I was concerned about particles getting through that light foam and hanging down in my goggles. I decided to rip out the styrofoam and use caulk or a hot glue gun to seal the holes. Maybe tuck both sides and leave the foam in. I didn't have time, but it might work. There are many nooks and crannies on this mask and fabric strap, you will need to soak everything in alcohol/sanitizer. for reliable decontamination. I'm sure you could adapt them to your needs. It's better than nothing, but if you want peace of mind you'll need to modify them and patch the holes.
