HydraPak Seeker 3L waterreservoir - Mammoth Grey

When you're miles from the nearest water source, carrying enough hydration without the bulk is a constant challenge.

Tips

For best results, rinse before first use and allow to air dry completely before storing. When using with a filter, ensure the threads are clean and dry before attaching. To freeze, fill only to 80% capacity to allow for expansion. Store away from sharp objects to maintain the integrity of the TPU material.
