COMBAT ARMS MED EAR PLUGS
3M Combat Arms Earplugs
Protect your hearing with these 3M Combat Arms Ear Plugs. These earplugs feature a special acoustical filter that lets lower-level sound through with relatively little noise reduction for greater situational awareness and provides an increasing amount of noise reduction as sound levels increase above 110dB. You can open or close the small filter switch to choose between modes.
