Nalgene Narrow Mouth Sustain Tritan Water Bottle - 1000ml - Grey




The Nalgene Narrow Mouth Sustain Tritan water bottle is designed for hikers, gym-goers, and everyday commuters who need a reliable, leak-proof hydration solution. With a 1000ml capacity and a narrow drinking aperture, it provides a controlled flow that is ideal for drinking on the move, though it does require a bottle brush for thorough internal cleaning compared to wide-mouth alternatives.

Yes, all Nalgene Sustain products are manufactured without BPA and BPS.
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.
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.
We do not recommend freezing the bottle solid, as the expansion of water can cause the plastic to crack or the lid to warp.
Yes, Nalgene caps are modular and you can purchase replacements if the original is ever lost or damaged.
Carbonated drinks can cause pressure buildup. It is best to avoid using this bottle for soda or sparkling water.
Ensure the threads are clean and free of debris. If the lid is 'cross-threaded', back it off and realign before tightening again.
Fill the bottle with a mixture of warm water and a small amount of baking soda. Let it sit overnight, then rinse thoroughly.
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.
