New for 2019: Premium taste-free hydration reservoir with 50% faster flow rate. Introducing the Big Zip™ EVO—the latest evolution in taste-free hydration. The Big Zip EVO delivers a significantly higher flow rate than previous Platypus reservoirs and a host of new features, making it a great option for backpackers, hikers, and mountain bikers. Available in 1.5L, 2.0L, 3.0L

NEW: Replacement valve with leak-proof control built for Big Zip™ EVO Reservoirs. The Big Zip™ EVO Shutoff Valve is a new leak-proof valve made specifically for the Big Zip™ EVO Reservoir. The improved design offers a wider angle for faster water flow, an embossed water droplet icon to indicate when water flow is engaged (taking away any guesswork on whether or not water is in on or off mode), and a larger on/off lever for ease of use (even with gloves on). The result is a valve that offers faster water flow and a more intuitive on/off lever.

UPDATED: Protects bite valve from dirt and debris; slows freezing. Whether you set down your pack on the muddy trail or in the snow, protect what goes into your mouth from dirt and debris while slowing down the freezing process with the updated Platypus® Bite Valve Cover. The new shape ensures your cover stays closed and it fits with all Platypus hydration system bite valves.

NEW: Insulates to prevent freezing and keeps water cool in the heat. Fend off frozen drink tubes and help keep liquids cool in hot weather with the Drink Tube Insulator. The new design offers a completely covered bite valve (to keep it clean and protect it from freezing quickly), a reverse coil polyurethane-coated zipper (to prevent ice/snow build up), a large zipper pull (to easily open with one hand—even with gloves on), and a hook and loop closure shoulder strap attachment (to secure to a pack). Works with all Platypus® drink tubes and bite valves.

UPDATED: Ultralight taste-free, minimalist reservoir with high flow rate. The original Platypus® water reservoir that became a backcountry classic, the Hoser™ is an ultralight, minimalist hydration system that delivers taste-free hydration with a versatile, durable design that makes it great for backpacking, thru-hiking, and day hikes. Updates include a new self-sealing HyFLO™ bite valve that delivers a 30% increase in flow rate, making it quicker and easier to hydrate on the go.

NEW: Lightweight, magnetic clip secures drink tube for easy retrieval. Magnetically clip your reservoir's drink tube right where you want it for easy retrieval. Just attach the clip to your pack strap or clothing and hook its magnetic mate to the hose to secure your drink tube. This accessory fits both 1/4"and 5/16" diameter drink tubes.

Set of 2 brushes cleans hydration reservoirs and drink tubes. Keep your hydration reservoir and drink tube fresh and clean with this easy-to-use 2-brush set. The broad head brush is designed to scrub the interior nooks and crannies of your reservoir while the thin, coiled brush scours your drink tube for a thorough, good-as-new clean.
