Product Information
Full details
This Hydro Flask 12oz Wide Mouth Flex Coffee Flask in Blue is designed for individuals who need to keep their hot beverages hot or cold drinks cold throughout the day. Its key benefit is maintaining ideal drink temperatures for up to 12 hours hot and 24 hours cold, with a caveat that the Flex Sip Lid, while leak-proof when closed, is primarily designed for drinking on the go and may require more careful handling with extremely hot liquids than a dedicated thermos. This flask features double-wall vacuum insulation, durable stainless steel construction, and a BPA-free, phthalate-free design.

FAQs
Is this flask suitable for carbonated beverages?
No, this flask is not designed for carbonated beverages. The pressure buildup can cause the lid to leak or even burst.
How long will my drink stay hot/cold?
The TempShield™ double-wall vacuum insulation keeps cold drinks cold for up to 24 hours and hot drinks hot for up to 12 hours. Actual times may vary based on external temperature and usage.
Can I put this in the freezer?
It is not recommended to put the flask in the freezer, as this can damage the vacuum insulation and potentially cause the bottle to crack.
How do I clean the Flex Sip Lid?
The Flex Sip Lid is top-rack dishwasher safe. For a thorough clean, you can often disassemble the twist-top portion and wash all parts with warm, soapy water. Ensure it is completely dry before reassembling.
Is the blue color fade-resistant?
Hydro Flask uses a durable powder coat finish that is designed to resist fading and chipping under normal use.
What is the warranty on this product?
Hydro Flask typically offers a limited lifetime warranty against manufacturing defects. Please refer to the official Hydro Flask website for current warranty details and registration.
Can I use this flask with very hot liquids like boiling water?
While the flask is designed for hot beverages, the Flex Sip Lid is primarily intended for on-the-go drinking. For extremely hot liquids, exercise caution and ensure the lid is securely fastened. It is recommended to allow extremely hot beverages to cool slightly before sealing and transporting.
Troubleshooting
Flask is not keeping drinks hot/cold as expected.
Ensure the TempShield™ insulation is intact. Check that the lid is screwed on tightly and properly sealed. Avoid opening the lid frequently. If the flask has been dropped, the insulation may be compromised.
Lid is difficult to open or close.
Check for any obstructions or dried residue around the threads or sealing surfaces. Clean the lid thoroughly. Ensure the lid is aligned correctly before twisting.
Leaking from the lid.
Verify that the Flex Sip Lid is screwed on completely and tightly. Inspect the silicone seal on the lid for any damage or debris. Ensure the lid's twist top is fully closed.
Exterior is sweating (condensation).
This indicates a failure of the vacuum insulation. Contact customer support if the flask is under warranty. This should not happen with intact vacuum insulation.
Metallic taste from the drink.
Rinse the flask thoroughly before first use. Wash with warm, soapy water and a bottle brush. If the taste persists, try soaking with a mixture of baking soda and water.
