The Platypus Hoser Hydration System will fit into just about any rucksack. Fill the bottle with water, and the hose can be clipped on your front to your lapel or rucksack strapping. The leak-free bite valve means you have access to a drink whenever you need one. No need to stop to find a water bottle - just get on and enjoy the outdoors.
Ideal for walking, mountaineering, biking, horse riding - and we found it great having one when out with a small child who needed regular sips.
Packable design flattens to roll up when empty to save space
Embedded silver-ion protects reservoir from mould & bacteria.
