**What is covered?**

*   Hydro Flask Hydration, Tumbler, Coffee, Beer, Wine & Spirits, Food, Large Capacity Hard Goods, Hard Good Accessory Products and Journey Series 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. 
*   Replacement parts will be utilized to address defects when available.

**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
