Our Verdict

Hydrapak’s updated Seeker 4L allows you to store water without adding too much weight or taking away too much pack space. The beauty of a soft bottle lies in the fact that, once empty, it compacts to an impressively small size. I can honestly say I have not used another water storage system that weighs this little, holds as much water and packs down as small as this does whilst still being as durable. The updates see a slight change in dimensions with this version becoming much longer and narrower for easier storage. The tear resistant, removable tether for the cap is a nice addition too and make it easier to use when you’re juggling a full water pouch when filling or decanting.

This versatile hydration system is ideal for carrying extra water on a hike or anywhere else you need water and carry space is limited. It even comes with it’s own handy little storage sack.
