Made for the outdoors.

Hydro Flask’s TempShield insulation has redefined what the classic outdoor water bottle can be. The 32 oz keeps your beverage icy cold or piping hot from trailhead to summit and every step in-between. Your perfect “all day and into the next” refreshment solution.

Replacing the existing cap on all our Wide Mouth bottles, the new award-winning Flex Cap is the ideal combination of strength and flexibility. Designed for ultimate portability, we crafted every detail with easy-carry comfort in mind – and insulated it too– so you can go further, for longer, keeping your favorite beverage comfortably by your side.

Restore flow rates in your AutoFlow Gravity Filter by replacing a tired, worn cartridge with fresh, new Hollow Fiber media.

This extra-large AutoFlow gravity filter system delivers 10 liters of clean water fast—all while you set up camp, prep dinner or relax. And its big capacity means fewer trips to the river to haul the water you need. Similar in packable size to a 4L system, the AutoFlow XL system's durable flat base doubles the water volume for only 340 g (12 oz) of total weight. Ultralight and supremely packable, it offers the luxury of pump-free group filtration for basecamps, scout troops, horsepackers and other backcountry groups. And just one 10-liter fill of the reservoir can supply 1-2 people with a whole day’s worth of clean water.

The Big Zip™ Drink Tube Kit easily replaces a damaged or old drink tube on your Platypus Big Zip™ EVO Reservoir. Grab a separate kit for a partner or each member of the family if sharing reservoirs is on your agenda. Kits offer specific tube lengths optimized for each of the Big Zip EVO Reservoir sizes—1.5L, 2L, 3L & Lumbar 2L. Includes a drink tube with quick-disconnect fitting, a Big Zip EVO shutoff valve, lapel attachment, and a HyFLO™ bite valve.

Please note: The Lumbar 2L version does not include the additional tube length with the quick-disconnect fitting.

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 and a Lumbar 2.0L.

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.
