The Hydrapak Seeker 4L is an ultralight water storage solution for camping, hiking or any backcountry adventure. It can be folded/crushed to collapse down and folds under it's own flexible bail handle.
Hydrapak says:
Go the distance with our latest addition to the Seeker series, the 4L. It has a higher capacity storage, yet it’s lightweight. The flexible bail handle allows for easy pouring and carrying. It packs away nice and easy. And four side lash points for hanging or pack attachment make it the perfect tool for the long haul.
Hydrapak's Seeker 4 Litre Water Storage has a few more features than the 2 and 3L versions. It is wider to increase stability and this is improved with the use of two internal baffles which stop the pouch stretching outwards when full. The same high quality TPU material is used keeping it super flexible and durable so it is perfect for collapsing and storing when not in use. There are additional lash points so that it is easier to attach to your pack and carry along with a small flexible bail handle for holding onto when filling and emptying it. This handle doubles up as a way of securing the whole pouch when empty and folded up.
The ability to add a water filter directly to the mouth of the Seeker is a massive bonus and it is compatible with the Katadyn BeFree Filter for those remote adventures where water sources may not be up to standard. If you need this much water or want the convenience of having extra water available at camp, this lightweight option is fantastic. It has been thoroughly used and abused on recent trips and shows little signs of use other than some scratches on the lid.
