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. A smart setup is to use the Vecto with a water filtration system. The 42mm opening is compatible with the Katadyn Befree.
This is a perfect addition to my on trail water purification set up
It was great between my 1L Hydrapak Flask and 1L BeFree Filter Soft flask the CNOC Vecto 2L made it easy to just fill everything at one time and have enough water at camp! Perfect!
