As far as we’re concerned, the hydration reservoir is one of hiking’s great inventions. We sure don’t miss having to take off a heavy pack halfway up a mountain, just to retrieve a water bottle in order to slake our raging thirst. And Platypus water reservoirs are rightly top of most outdoor adventurers’ lists when it comes to hands-free hydration. The Hoser is an ultralight, minimalist hydration system that delivers taste-free water, so no more mouthfuls of disgusting plastic-tasting swill. Their durable design means you don’t have to worry about leaks, even if your pack gets squished, and they aren’t bulky like many other hydration pouches, so they stow neatly in your pack. Complete with a self-sealing HyFLO bite valve that delivers a 30% increase in flow rate, hydration on the go has never been so easy. They’re easy to fill and clean too, although thanks to embedded silver-ion technology, the reservoir is protected from mould and bacteria.
