Simply foldable

The Seeker bag is simply foldable. After packing, you can fold it into the included storage bag. In addition, it has multiple uses. You can freeze it and use it as an ice pack or keep it on hand as part of a camp kit to combine with a filter bag.

Compatibility with filtration

You often cannot be sure that the water you come across in nature is potable. Therefore, filtration is a suitable solution. You can screw most filters with a 42 mm thread on top of the HydraPak Seeker, such as the Katadyn BeFree Filter, but also the HydraPak Cap filter, which in this case is included in the package.

Get drinking water even on the go

Although, especially in our conditions, we can often find harmless clean water in nature, the motto "trust, but verify" should apply. The Cap water filter is a great tool for that inspection. With the help of original HydraPak products, you can pour water into other containers through this filter, or drink freshly filtered water directly from them.

The complete HydraPak solution

The American brand HydraPak offers a complete solution with the Cap water filter, which you can use not only with Seeker products, but also with Flux, UltraFlask or SkyFlask bottles. In any case, you will enjoy easy and quick water treatment, whether in the camp or directly in the field.

Lightweight and compact solution

At only 57 grams, the Cap filter is one of the lightest filter solutions on the market. Such a filter takes up practically no extra space, whether you decide to store it separately in your backpack or screw it directly onto the Seeker or Flux products for transport.

Dust cover and powerful nozzle

The high-flow drinking nozzle has a dust cover that prevents the accumulation of dirt. In addition, you can open and close the powerful beverage nozzle with one hand without direct contact with dirty hands.

The HydraPak Cap water filter is completely safe and reliable. Removes Escherichia coli bacteria, Cryptosporidium parvum cysts and Giardia Lamblia (99.9 %) from approximately 1500 liters of water. It even protects against microplastics. In this regard, it meets or even exceeds EPA protocols. In addition, it is not harmful in itself. It does not contain bisphenol A (BPA) or PVC.

Compatible with 42mm thread

Thanks to the 42mm thread, you can screw the filter onto most popular water storage bags, flexible bottles and running bottles.

Easy to carry, the HydraPak Seeker collapsible bag features both a tear- and weather-resistant pouring handle and a flexible design that makes the bag so light and compact that you'll forget it's in your pack - especially when it's folded and empty.

Easy filling

The large 42mm opening makes filling the Seeker bag easy, and the attached screw cap prevents the cap from being lost. The lanyard, in turn, creates a practical loop to keep the Seeker upright while filling.

Can be attached to a backpack

Two load-bearing side tie-down points allow the HydraPak Seeker to be attached to a backpack or set up as a gravity dispenser. There is a capacity indicator on the outside, which in turn allows you to monitor fluid intake or measure the content.
