This hydration reservoir delivers a significantly higher flow rate than previous Platypus hydration reservoirs and adds many new features, making it an ideal choice for backpackers, hikers, and mountain bikers.
Its secure SlideLock™ system, which slides in both directions, allows you to open, close, and refill your reservoir with complete ease and security.
Integrated silver ions keep your water clean and protected from mold and bacteria. All materials are certified taste-free, BPA-free, BPS-free, and phthalate-free.
Available in capacities of 1.5 liters, 2.0 liters, 3.0 liters, and a 2.0 liter lumbar version.
