FAQs

Is the Hydro Flask 355 ml mug leak-proof?

No, it is splash-resistant, meaning it handles minor splashes but is not designed to be tipped over or carried inside a bag.

Can I put this in the freezer?

Freezing is not recommended, as it can damage the vacuum seal and affect the mug's insulation properties.

Is the stainless steel BPA-free?

Yes, all Hydro Flask products are made with 18/8 food-grade stainless steel and are free of BPA.

Does the exterior sweat when holding cold drinks?

No, the TempShield double-wall vacuum insulation prevents condensation on the outside of the mug.

Can I use this mug for carbonated beverages?

It is not recommended for carbonated beverages as pressure buildup can cause the lid to pop or leak.

Troubleshooting

Lid feels stiff or difficult to slide

Remove the lid and soak in warm soapy water to dissolve dried coffee residue. Ensure the silicone gasket is properly seated.

Drink is not staying hot for as long as expected

Pre-heat the mug by filling it with boiling water for a few minutes before pouring in your coffee. Ensure the lid is firmly pressed on to create a proper seal.

Setup, Compatibility & Care

To begin using your Hydro Flask, simply wash the vessel and lid with warm, soapy water before the first use.

  • Compatibility: The 355 ml size is compatible with most standard single-serve coffee machines and fits in common automobile cup holders.
  • Cleaning: Place both the mug and the lid on the top rack of your dishwasher. If washing by hand, use a soft bottle brush to reach the bottom without scratching the interior finish.
