How do you protect the respirator that protects your lungs? With a GVS Hard Carry Case! This low profile hard carry case is perfect for protecting your respirator when it isn’t around your face. Protection is vital, because when your mask gets damaged it loses its seal, which weakens the mask’s integrity. This hard case will prevent that problem and extend the mask’s life. A nylon loop on the back of the case allows it to be worn on a belt or be attached to a clip.
