**What is covered?**

*   MyHydro products carry a limited lifetime warranty against manufacturer’s defects for the life of the product. 
*   Hydro Flask will replace any product found to be defective within the scope of normal and appropriate use. 
*   We will not be able to offer the complete configuration as a full warranty.  We will handle each warranty on a case-by-case basis but cannot guarantee every piece of your MyHydro will be available for warranty.
*   Those that have purchased engraved flasks will not get an engraved flask sent to them under our warranty replacement policy.

**What is considered defective?**

*   Flask loses insulation property 
    1.  Flask could lose its insulation property if the cap/lid is defective or if the flask’s insulation wall is compromised
    2.  You can test the insulation BEFORE submitting a warranty replacement
    3.  See instructions by clicking: [Flask Insulation Test](https://hydroflask.kustomer.support/en_us/flask-insulation-test-B19yBQ_Ns)
*   Rattling flasks
    1.  The rattle you hear is a small metal disc that sits between the double wall of your flask and aids in the vacuum insulation process. 
    2.  Sometimes the disc becomes dislodged, creating a small noise or rattle. 
    3.  This will not affect the insulation or structural integrity of your flask.
    4.  If it is an annoyance, we will cover it under our Limited Lifetime Warranty
