Grunge-Guard™

An unpleasant characteristic of hydration bladders is the likelihood of a thin film of sediment settling on the walls and the subsequent growth of bacteria in this often nearly imperceptible layer. The company's Grunge-Guard™ technology is aimed at addressing this problem by coating the interior surface of the bladder with a thin layer of special plastic containing antimicrobial additives. These additives are, of course, completely safe, approved by the FDA and registered with the EPA. The additives are a permanent part of the layer, do not leach into the drinking water or cleaning solution, and the layer maintains its antimicrobial effect throughout the lifespan of the hydration bladder.
