Setup, Compatibility & Care

To ensure the longevity of your Nalgene flask, always rinse the container with warm, soapy water before its first use. The 2-part design allows you to separate the body to reach interior corners with a bottle brush. While the flask is durable, it should not be subjected to extreme heat. Ensure the cap is fully tightened before placing it in a bag to maintain the leakproof seal. For storage, keep the cap off when not in use to allow the interior to air dry completely, preventing trapped moisture.
