I'm seriously considering buying an Airshield because I'm growing tired of putting on and taking off ear plugs, respirator, eye protection, and ear muffs (yes I wear 2 layers of ear protection--29 dB + 25 dB. I have 3 questions.
1. Does the Airshield have some built-in ear protection?
2. Is it one size fits all?
3. Is the eye protection comparable to safety glasses?
