Seeker 4L Water Bottle

Designed for the backpacker and hardcore hiker in need of hydration, the Hydrapak Seeker 4L Water Bottle carries plenty of hydration when you're miles from the nearest water source. This lightweight water repository is the largest offered by Hydrapak, storing an impressive 4 liters (that's 135 ounces) of water while you're camping off the grid, walking long distances on the trail, and hiking in sweltering conditions. It comes with four-side tie downs, so you can hang it from a structure at basecamp or tie it to your pack on the trail. Additionally, there's a screw-on cap for a secure closure without any precious water spilling out.

Seeker 4L Water Bottle

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.

4 L Hydrapak

I've put it through the wringer

This is bottle is perfect! It fits nicely into my pack and collapse down nicely for easy storage once it is empty. Plus it is surprisingly durable!


The Seeker 4L

Check out the Seeker. Best way to carry a lot of water.

Water storage without the bulk

I've used it several times

I love this water bottle! Me and my dogs drink a lot of water, and on our hikes or adventures we go through a lot. The worst part was you pack it in and once you're out of water you're lugging around a large bottle. Not anymore! I love that once the water is gone this bottle packs up and stows away!
