Abstract
A water bladder system. An air valve, which may be a check valve, is configured to be coupled with the flexible container and selectively allow air to enter an interior of the flexible container. A release mechanism coupled with the flexible container selectively allows the fluid to exit the interior of the flexible container. An open-celled foam is included within the interior of the flexible container and is coated with a quaternary organosilane coating produced from a quaternary ammonium organosilane reagent.
