Hydrapak Seeker Foldable Water Bottle 3L Mammoth

Hydrapak Seeker Foldable Water Bottle 3L Mammoth

The Hydrapak Seeker 3L from Bullseye Country Sport is an ultra-lightweight and highly packable hydration solution designed for hiking, camping, travel and long outdoor adventures where saving weight and space matters. Built for backcountry use, the Seeker combines the portability of a soft flask with the capacity and practicality of a larger water storage system.

Constructed from durable abrasion-resistant TPU with reinforced welds, the Seeker is designed to handle demanding outdoor conditions while remaining flexible enough to roll or flatten down when empty. Its lightweight construction makes it particularly useful for hiking packs, camping kits and travel setups where bulky rigid bottles can quickly become awkward or inefficient.

The large 42 mm opening makes filling, pouring and cleaning simple, while the tethered screw cap prevents accidental loss during use. A weather-resistant carry and pour handle allows easy handling around camp or while refilling, and the integrated side lash points provide convenient attachment options for backpacks and outdoor gear.

Designed with versatility in mind, the Seeker is compatible with 42 mm filtration systems, allowing it to work as part of a lightweight outdoor water filtration setup. It can also be frozen and used as an ice pack or cold water reserve during warmer conditions, making it a genuinely practical addition to camping and expedition gear.

When empty, the Seeker packs down to a fraction of the size of a traditional hard bottle, making it ideal for long-distance hiking, bushcraft, camping, overlanding and emergency preparedness kits where efficient storage is important.

Finished in the Mammoth colourway, the Seeker combines practical outdoor functionality with Hydrapak’s well-known lightweight design philosophy and durable construction standards.

At Bullseye Country Sport, we reckon lightweight camping gear always starts with “saving a bit of pack weight”… then somehow turns into people cutting labels off their toothbrush.
