Platypus Big Zip EVO 2 L Hydration Reservoir System for Hiking

The Platypus Big Zip EVO 2 L is a high-performance hydration reservoir system engineered for hikers, backpackers, and mountain bikers who require reliable, taste-free water access. This 2-liter bladder features an advanced design that prioritizes ease of use, efficient water flow, and durability during long outdoor excursions. Its slim, semi-rigid profile allows it to fit comfortably into most standard hiking backpacks, ensuring stable weight distribution while you are on the move.

Advantages

This hydration system stands out due to its significantly improved flow rate, facilitated by a larger drink tube and a high-performance bite valve. The reservoir is constructed from materials that are certified taste-free, BPA-free, BPS-free, and phthalate-free, ensuring your water remains fresh without any plastic aftertaste. The inclusion of silver-ion technology helps protect the water from mold and bacteria, keeping the system hygienic over time. Additionally, the semi-rigid center baffle maintains a low profile even when full, which also simplifies the process of cleaning and drying the reservoir after use.

Suitable for

• Hiking and backpacking trips
• Mountain biking adventures
• Long-distance trekking
• Outdoor activities requiring hands-free hydration

When it may not be suitable

This reservoir may not be ideal for activities where extreme freezing temperatures are expected, as the tube and valve can be prone to freezing without additional insulation. It is also not designed for use with carbonated beverages, juices, or alcohol, as these can damage the internal components and are difficult to clean from the bladder.

How to use

To fill the reservoir, use the SlideLock closure, which slides in both directions to provide a wide opening for easy access. The integrated pincher grip allows you to hold the bladder securely with one hand while filling it. Once filled, slide the lock shut to ensure a leak-proof seal. Connect the drink tube using the high-mount quick-disconnect feature, which allows for easy attachment and removal from your pack. When drinking, simply bite the HyFLO valve to release water, and it will self-seal automatically once you release pressure.

What to consider before purchase

• Check if your backpack has a dedicated hydration sleeve and routing port for the tube.
• Ensure the 2-liter capacity meets your hydration needs for the duration of your planned activity.
• Consider purchasing a cleaning kit if you plan to use the reservoir frequently in varied environments.

Usage recommendations

For optimal hygiene, always empty the reservoir and allow it to dry completely after each use. Store it in a cool, dry place away from direct sunlight to maintain the integrity of the materials.
