In general, you can use ANY hydration system that meets your requie,ents. There are many different hydration systems on the market, each with different features. However, we recommend the 2L OR 3L STEAMER HYDRATION SYSTEM FROM DEUTER. This system is particularly robust, easy to handle and offers sufficient capacity for longer trips.
But regardless of which hydration system you choose, the hydration system preparation is included in every current ORTOVOX backpack. We make sure that you can use your hydration system easily in our backpacks without any problems. This includes, among other things, a special compartment or a device to hold the drinking tube.
