HydraPak Seeker 3L vandbeholder - Mammoth Grey

When you're miles from the nearest water source, carrying enough hydration without the bulk is a constant challenge. The HydraPak Seeker 3L Water Container solves this by giving you a full three liters of capacity in an ultra-packable, flexible design that collapses to a fraction of its filled size. Made from durable TPU with RF-welded seams, it's built to handle rugged trails and repeated use, while the 42mm screw cap ensures a leak-proof seal and compatibility with most 42mm threaded filters like the Katadyn BeFree.

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.
