Platypus Hoser Reservoir 3.0L Hydration Pouch | Review

Stay hydrated with this ultralight, minimalist, and efficient taste-free water storage solution

Why We Chose The Platypus Hoser Reservoir 3.0L Hydration Pouch: High spec design, minimalist look, clever bacteria-halting tech

When it comes to keeping outdoor enthusiasts hydrated, the folks at Platypus are definitely right up there in the expert bracket. What these self-proclaimed “water geeks” don’t know about their specialist field, quite frankly, isn’t worth knowing. Their Hoser Reservoir 3.0L Hydration Pouch is a great example of taking a seemingly simple type of product, and taking it to the next level. For this reason, and numerous others, we’ve decided to include it in this year’s Outdoor 100.

Who Is The Platypus Hoser Reservoir 3.0L Hydration Pouch For?

It should go without saying that if the thought of being dehydrated in the outdoors sounds like your idea of a bad time, then this water storage solution is for you. More specifically than that, however, the Hoser 3.0L Hydration Pouch is a product aimed at outdoor enthusiasts who might have to go long periods of time outdoors without fresh, clean, water and who want their rehydration to be as quick and convenient as possible.


Made from a mixture of Polyurethane, Polyethylene, and Silicone – all the materials used are certified taste-free, BPA-free, BPS-free and phthalate-free.


For what, on paper, is a plastic pouch for your hiking water the Hoser 3.0L has a genuinely surprising amount of interesting features (that’s why we’ve included it in the Outdoor 100).

The simple, yet incredibly clever, one-piece self-sealing HyFLO bite valve makes, for example, makes it quicker and easier than ever to hydrate hands-free. It delivers a highly efficient 30% increase in flow rate than previous bladders.

It’s super transportable and it’s also incredibly versatile.

Another great, pretty clever, feature on the Hoser Reservoir 3.0L Hydration Pouch is the embedded silver-ion that essentially protects the reservoir from mould and bacteria. Good because, let’s face it, who wants mould and / or bacteria in their reservoir.

With its integrated hang / carry loop, which makes it easy to secure the reservoir in a backpack, the Hoser Reservoir 3.0L Hydration Pouch is super transportable and it’s also incredibly versatile, with its threaded port and quarter-inch diameter drinking tube – features that make it compatible with accessory caps and adaptors.

The Platypus Hoser Reservoir 3.0L Hydration Pouch has an RRP of £28.99. Not cheap by any stretch, although in the same price bracket as similar products, this is one up-front investment that will serve you well in the long term – paying you back and then some on those hot, active, outdoor days where drinking water really is essential.

If you’ve got a big, post-lockdown, thru-hike planned, get one of these in your backpack.
