The EBH Backpack attaches securely and easily to Bullard’s EVA/EVAHL Powered Air-Purifying Respirators (PAPRs). Expertly designed to evenly distribute weight, the EBH provides users with increased comfort during long periods of standing, sitting, and kneeling. The versatile design allows the EBH to be worn traditionally on the back or chest (with longer breathing hose). EBH is also designed to accommodate a tool belt with the EVA/EVAHL PAPR by tightening the straps and positioning the backpack higher on the chest or back.
