I purchased two of the Platypus Hoser hydration systems – a smaller 1.8 liter one and the larger 3 liter model.
I was easily able to place the Platypus water reservoir inside the water pocket in my backpack. Plus, the water hose is easy to clip to the outside surface of the backpack for quick access.
Certain hydration systems need a while to prime, but with this model, there were no issues and the water started to flow in a matter of seconds. It certainly provides a reliable service.
It comes in a good selection of sizes, 1L, 1.8L, 2L, and 3L models available, and it is free of that annoying plastic taste some have, especially when new. It also collapses to a small packet when drained. Plus, it is really easy to clean and maintain.
In my option, the hydration pack is pretty darn good for those needing a replacement bladder. It is a great alternative to using standard water bottles.

The Platypus Hoser Hydration System
A versatile and classic-styled water reservoir, the Platypus Hoser provides complete simplicity and is insanely durable. It has a hanging hook which is a practical addition if ever needed to hang the pack (for filtering, pouring water, storage, etc). Plus, it has an alligator clip that isn’t made in the strongest material but is still a great part of the overall system.
A negative I noticed often when researching this pack related to the common complaint of a plastic taste on the first two or three goes. However, this wasn’t the case for me and I didn’t notice any plastic taste and the first outing and thereafter.
Plus, I didn’t notice any leaks in the backpack after traveling over difficult terrain for several days, which was an issue I was particularly concerned with.
One particular niggle with the device is the bite value which doesn’t shut off particularly well. So if you are planning to overnight at a campsite, a separate cap might be needed to double up the pack’s use as a water storage option. But, overall it is a reliable option for day trekking.
Also, a further thing that isn’t the best is the time it takes to completely dry out the bladder pack. The small opening means I’m not able to use anything to help dry the bladder, so it needs to be left out to dry to avoid issues with mold.
Summary
This is a really good bladder, available in a variety of sizes. It performs well and will not break the bank.
So if you need a replacement or an upgrade to some of the cheaper ones that are supplied, this is definitely worth shortlisting.
