Deuter Streamer hydration system is a necessary companion for your outdoor activities. It manages keeping fit for longer and enables regular hydration without interrupting sports activities. Deuter backpacks are specially coordinated with the drinking system. The drinking system can be easily filled and cleaned thanks to its wide opening which expands over the whole width – absolutely leak free due to the push clip closure. The attachable protective cap keeps the mouthpiece free from dirt during longer journeys.
