The headgear has right and left symmetrical earguard assemblies with an earguard pad and protective shell that are detachable from each other. A plurality of detachable head straps join each earguard assembly to prevent separation of the pad and shell of each earguard assembly. The periphery of each protective shell is surrounded and embraced by peripheral wall portions on the pads to align the respective shells on the respective earguard pads in an alignment position. Corresponding engageable protrusions and recesses on the pads and shells also help maintain the alignment position. |
