It will depend on the size of your Kanken. If not, you may want to consider an Exo Case.
All Camelbak water bottles are compatible with most kankens - this includes in-store purchases in either Australia or in the US, as well as with international shipments for sale or samples that are sent to client offices or potential retailers around the world. This includes all sizes of the lids and valves found on our QuickChill, Eddy, Military Series CamelBak Hydration Packs and also bottle-only models like The Straw Bottle.
Bottles don't need a kanken specifically designed for water bottles because all available options are suitable for use by most hikers.
