How to Choose the Right HydroJug Size
When deciding which HydroJug size to buy, here are a few tips:
- Consider your hydration needs. How much water do you normally drink in a day? Pick a larger size if you drink a lot of water.
- Think about where you will use it. Larger HydroJugs may not fit in your car’s cup holders or your backpack as easily. The 12-24 oz sizes are most portable.
- Look at your daily habits. The smaller HydroJugs like 12-21 oz are good for short trips out while the 32-64 oz jugs allow you to go longer between refills.
- Factor in intensity of activity. Larger HydroJugs are great for vigorous exercise, hiking, festivals, or travel when you need to hydrate heavily.
- Pick a narrow mouth style if using cup holders a lot. The wide mouth is easier to add ice but won’t fit in holders.
Choosing the right size comes down to your own hydration needs and drinking habits. Once you buy a HydroJug, you’ll wonder how you ever lived without it!
