My Ultralight Hydration & Gravity Filtering Kit

This hydration kit is what I take for filtering water on backpacking trips. It’s compact, simple to use, and very lightweight.

Shown above:

Total storage capacity with this system: 5 liters (add another Hydroblu canteen for 7 liters of capacity)

Total weight of this setup: 10 oz.

For easy access to water while I’m hiking, I add a hydration hose with a bite valve to the SmartWater bottle. It’s important that the hose is inside the bottle, pushed all the way in so the water is pulled up from the bottom. I use this tube and cap setup and place the water bottle in the side pocket of my backpack.
