HydraPak hydration reservoir SEEKER 10L Mammoth Grey — 10 L capacity, roll-top closure, lightweight bladder

HydraPak SEEKER 10L Mammoth Grey is a 10-litre hydration reservoir designed for carrying and dispensing water on outdoor trips. The flexible bladder has a roll-top closure that provides a secure seal and a wide opening for easy filling and cleaning. A hose outlet allows connection to a drinking tube or direct pouring, making the reservoir suitable for extended hikes, multi-day expeditions, and basecamp water storage.

Advantages

The roll-top closure offers reliable sealing and simple access without complex clips. The wide-mouth opening facilitates rapid filling from bottles or streams and simplifies thorough cleaning and drying. The lightweight construction reduces pack weight while the large 10 L capacity supports longer trips or groups. The hose outlet is positioned for convenient attachment to standard drinking tubes or for filling containers without removing the bladder.

Suitable for

• Extended hiking and backpacking trips where high water capacity is required
• Camping and basecamp water storage for groups
• Multi-day expeditions and remote travel where refill points are scarce
• Emergency preparedness and home water reserve

How to use

Open the roll-top closure, unfold the reservoir and fill with potable water up to the recommended level while avoiding overfilling. Fold the roll-top securely and fasten according to the fold count to create a leak-resistant seal. Route the hose from the outlet and connect a drinking tube or spout as needed, securing the bladder in a pack or storing it flat at camp. After use, empty the bladder, rinse with clean water and allow the interior to dry fully before storing to prevent odour and microbial growth.

Usage recommendations

For longevity, avoid prolonged exposure to direct sunlight and do not store with liquid inside for extended periods. Clean regularly using mild soap or a cleaning kit specifically designed for hydration reservoirs. When using in cold conditions, insulate the hose or keep the bladder close to your body to reduce the risk of freezing.
