Keeping hydrated is key to human life. Without water and essential nutrients we cannot perform at our peak. Hydra is a liquid distribution system that swiftly and accurately delivers hydration whenever and wherever it is needed during sports play. Hydra launches prefilled, biodegradable spheres containing the precise amount of water and electrolytes needed for intense sport sessions where opportunities for rehydration are few and far between. Hydra has the potential to move into the public domain, providing refreshments on demand in stadiums, on the street and in local parks.
