Typical hot packs require high heating temperatures to kill the bacteria that can enter through their porous coverings. HydraHeat Packs don't have a porous outer layer like conventional heat therapy packs, so HydraHeat treatments can occur at lower, safer temperatures, while still being within the therapeutic range.

• Polymer Skin is Bacteria Resistant and Easy to Wipe Clean, Lessening the Risk of Bacterial Attachment
