The hydration systems allow for a continuous supply of liquid without the need to interrupt physical activity. The small drinking pouch with its unique shape is specifically designed to fit the Pulse 3 hip pack. Thanks to the side flaps of the drinking pouch, the available space is optimally utilized, and there is still room for tools and snacks in the hip pack. The drinking tube has a standard length and is compatible with all other hydration bladders in the range. The entire system is free from BPA and PFC. Taste-Free: The inner surface of the hydration bladder and the tube is as smooth as glass. Due to these molecular material properties, the Streamer is taste-neutral, very hygienic, and easy to clean. Grunge-Guard: This coating, which is firmly bonded to the carrier material, prevents the settlement of bacteria in the hydration system. Easy Clean: The hydration bladder can be conveniently filled and cleaned through the large opening that spans the entire width - completely leak-proof thanks to the slide-clip closure. Dirt Guard: The attachable protective cap keeps dirt away from the mouthpiece during extended transport.
