The hydration systems allow for a continuous supply of liquid without having to interrupt physical activity. The small hydration bladder with its unique shape is specifically designed to fit the Pulse 3 hip pack. Thanks to the side flaps of the hydration bladder, the available space is optimally utilized, allowing room for tools and snacks in the hip pack as well. The drinking tube is of 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 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 across its 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.
