Measurements: Each bottle is 2.5 Litres with a trigger hose. Nothing takes the fun out of being outdoors like getting wet. Over time even the best outdoor gear will begin to lose its ability to repel water. This is because dirt, dust, and other impurities, as well as general wear, will create a problem for your gear. Our specially formulated tent and gear waterproof 2.5 Litre spray effectively protects tents and gear from the elements.
