When rack space is tight, every pound matters, or you just need a compact water supply to round out your build, the RotopaX 1 Gallon Water Storage Pack is the right call. It is the smallest water pack in the RotopaX lineup — easy to tuck onto a spare tire carrier, MOLLE panel, or side rail without taking up real estate you need for other gear. One gallon goes a long way as a secondary water source, an emergency reserve, or a dedicated hand-washing station at camp.
Construction is the same thick-walled roto-molded plastic used across the entire RotopaX lineup, with a sure-seal gasket that keeps everything leak-proof whether the pack is mounted on a rack, strapped to a bumper, or sitting in a truck bed. All materials are BPA-free and safe for drinking water storage. Like every RotopaX water pack, it can be frozen to keep cold water on hand throughout the day — a straightforward feature that makes a real difference in summer heat.
At 13.5 inches tall, 9.5 inches wide, and just 3 inches deep, the 1 gallon has the same slim profile as the 1 gallon gasoline pack, making it easy to pair the two on the same mounting setup without adding bulk. It is compatible with the full RotopaX mounting system using Standard, DLX, and LOX pack mounts, and can be stacked with other containers using the 1, 2, and 4 Gallon Extension. If you want spigot-style dispensing, the RotopaX Spigot Kit is available separately and threads directly onto the container.
