The CNOC Vecto is a soft, collapsible water container. Its patent-pending dual opening system allows for easy filling from a wide opening on one side, and a narrow mouthpiece on the other. A very popular setup is to use the Vecto with a water filtration system. The 42mm opening is compatible with the Katadyn Befree.
