RotopaX Water Pack Looking for a durable, compact solution to secure extra liquids on your ride RotopaX container presents the perfect option. This contraption is rotationally molded, making it significantly stronger than traditional blow-molded designs. It uses plastic that is resistant to both color fade and mechanical degradation, with a sure-seal gasket guaranteeing a leak-proof structure. The design of each RotopaX Pack allows it to secure through its central port with an equipped RotopaX Pack Mount. This unique design supports the weight of the pack from its center, making it easier to find a mounting point on your bike as it requires a smaller footprint relative to the size of the pack. Ideal mounting locations could be on top case luggage racks, side case racks, or even attached directly to luggage systems. What's more, the design allows RotopaX Packs to stack on one another using a Pack Mount Extension, enabling you to increase capacity based on your needs. Note that Pack Mounts are sold separately.
