FAQs

Is the Nalgene Silo BPA-free?

Yes, all Nalgene Sustain bottles are BPA and BPS-free.

Will this fit in my car's cup holder?

Due to its 1.5-litre size, it is generally too wide for standard automotive cup holders.

Can I put boiling water in it?

Nalgene bottles are made of durable resin, but they are not intended for use with boiling liquids. Warm or cool water is recommended.

Is the bottle microwave safe?

No, it is not recommended to place your Nalgene bottle in the microwave.

Does the bottle come with a cap leash?

Yes, the Silo features an attached tether that keeps the cap secure to the bottle while drinking.

What material is it made of?

Troubleshooting

Cap leaking after use

Check the plastic threads for debris or damage and ensure the silicone gasket inside the cap is seated correctly.

Residual odors or tastes

Fill the bottle with a mixture of baking soda and water, let it sit overnight, then rinse thoroughly in the dishwasher.

Pros and Cons

Pros

  • Compatible with most water filtration systems
  • Extremely durable against impacts
  • Leakproof seal prevents messy spills
  • Easy to clean via dishwasher

Cons

  • May be too wide for standard cup holders

Setup, Compatibility & Care

To ensure longevity, wash the bottle thoroughly with mild soap and warm water before its first use. While the bottle is dishwasher safe, ensure it is placed on the top rack away from heating elements to prevent warping. The 63mm opening is compatible with most standard backcountry water filters, but verify that your specific filter attachment fits securely before venturing out. For routine maintenance, use a bottle brush to reach the base if you have been using the container for electrolyte mixes, which can leave residue. Always ensure the cap is tightened firmly to engage the leakproof seal, but avoid overtightening, which can stress the threads over time.
