Go the distance with plenty of hydration.

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.
  • Carries four liters of water while backpacking and camping
  • Lightweight, ultra-tough construction of TPU and HDPE
  • Four-side tie downs for hanging and attaching to packs
  • Screw-on cap provides secure closure without leaking
  • Folds down for compact storage when it's not needed

4 L Hydrapak

  • Familiarity: 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!

Water storage without the bulk

  • Familiarity: 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!
