Answer

HydroGuard is a CamelBak proprietary antimicrobial technology embedded directly into the Podium, Podium Chill and Podium Ice bottle walls, as well as CamelBak reservoirs, drink tubes, and Quick Stow. HydroGuard is an EPA-registered compound with anti-microbial properties that inhibit the growth of bacteria that can cause odors, discoloration or deterioration of the bottle. HydroGuard doesn’t protect against disease-causing organisms, though, and you should still clean your bottles after each use.
