The hydration systems allow a continuous supply of liquid without having to interrupt the sporting activity. The small hydration bag with the unusual shape is specially adapted to the Pulse 3 hip bag. Thanks to the side flaps of the hydration bag, the available space is optimally used and even tools and provisions still find room in the hip bag. The drinking tube has standard length and is compatible with all other hydration bladders in the range. The entire system is BPA and PFC free. Taste-Free: The inner surface of the hydration bladder and hose is as smooth as glass. These molecular material properties make the streamer tasteless, very hygienic and easy to clean. Grunge-Guard: This coating, stably bonded to the carrier material, prevents bacteria from settling in the hydration system. Easy Clean: Easy to fill and clean the hydration bladder through the large opening across the entire width - absolutely leak-proof by sliding clip closure. Dirt Guard: The attachable protective cap keeps dirt away from the mouthpiece during longer transport.
