FAQs

Is this bottle BPA-free?

Yes, all Nalgene Sustain products are manufactured without BPA and BPS.

Can I put boiling water in this bottle?

While the material is heat-resistant, it is not designed to be a thermos. It can handle hot liquids, but use caution to avoid burns when handling.

Does it fit in a standard car cup holder?

The 1000ml bottle is wide; it may not fit in all standard car cup holders. Check your vehicle's cup holder diameter if this is a priority.

Can I put the bottle in the freezer?

We do not recommend freezing the bottle solid, as the expansion of water can cause the plastic to crack or the lid to warp.

Is the cap replaceable?

Yes, Nalgene caps are modular and you can purchase replacements if the original is ever lost or damaged.

Can I use this for carbonated beverages?

Carbonated drinks can cause pressure buildup. It is best to avoid using this bottle for soda or sparkling water.

Troubleshooting

Lid feels difficult to screw on properly

Ensure the threads are clean and free of debris. If the lid is 'cross-threaded', back it off and realign before tightening again.

Bottle has developed an odor

Fill the bottle with a mixture of warm water and a small amount of baking soda. Let it sit overnight, then rinse thoroughly.

Pros and Cons

  • Leak-proof design ensures peace of mind in bags
  • BPA and BPS-free for safety
  • Environmentally conscious manufacturing using recycled resin
  • Clear volume measurements for tracking intake

Setup, Compatibility & Care

To begin using your Nalgene bottle, simply rinse it with warm water and mild soap before the first use. While the bottle is dishwasher safe, we recommend placing it on the top rack to avoid extreme heat concentrations. If you use it for sugary drinks or electrolyte powders, wash it promptly to prevent residue buildup. The narrow mouth is compatible with standard bottle brushes; avoid using abrasive scrubbers that could scratch the internal surface. The attached loop-top is designed to be tightened firmly to maintain its leak-proof status, but avoid overtightening, which can stress the threads over time.
