HydraPak Seeker

Because it is made from flexible TPU, the Seeker collapses down to about the size of a fist. It’s designed to be rolled or folded, making it easy to stash in a jacket pocket or a small corner of your pack when not in use.

The Seeker is primarily designed as a water storage vessel rather than a traditional hydration bladder. While it features a standard 42mm screw cap, it is not compatible with standard hydration hoses or bite valves out of the box.

The Seeker is built to be rugged, but it is not designed for boiling water. It can handle freezing temperatures, but be sure to leave some room for expansion if you plan to freeze it, as water expands when it turns to ice.

The wide-mouth opening makes cleaning straightforward. You can easily reach inside with a bottle brush to scrub the interior, and because the material is flexible, you can turn it inside out for a thorough rinse and air dry.

Yes, the Seeker is constructed from BPA-free and PVC-free TPU materials. It is designed to be taste-neutral, so your water won't have a plastic aftertaste, even after sitting in the reservoir for a while.
