PLATYPUS HOSER HYDRATION SYSTEM (3.0L) Platypus Hydration Systems Flexible, lightweight, durable and taste-free, Platypus is the modern way to keep hydrated during any outdoor activity. More versatile than metal canteens and rigid bottles, the bottles flatten when empty for convenient storage. Add a drinking tube for a hands-free hydration system, swap the bite valve for a Shower Kit or use the Filter Link for direct connection to your water filter. Platypus' triple-layer laminate is welded at the seams, highly durable and guaranteed leak-proof. In addition to water bottles, the range comprises easy-to-fill wide-mouth reservoirs, insulated bottle holsters and sophisticated all-in-one hydration backpacks. The Hoser The workhorse of the Platy family, our Hoser TM reservoir is the latest incarnation of a classic and versatile performer. It turns almost any pack into a hydration pack, or use it with a cap for drinking and cooking around camp. You can also customize it with a range of Platy accessories to suit even your most adventurous journeys. Closure cap NOT included. Platypus awarded Best Hydration System Brand as voted by readers of Dandelion Magazine (now Women's Adventure Magazine) in 2005.
