Flask

CAN I USE THE FLASK FOR HOT & COLD DRINKS?

This is a single-wall stainless steel Flask designed for cold beverages. We strongly recommend you not use it for hot, carbonated, or perishable beverages.

IS THE FLASK COMPATIBLE WITH ANY OTHER LIDS?

No, only the Flask cap is compatible with the Flask vessel.

IS THE FLASK DISHWASHER SAFE?

Sure is. We recommend placing the flask on the top rack and cap & funnel in the utensil basket. Of course, you can always hand wash, but we know you're busy with your next adventure.

IS THE FLASK LEAK PROOF?

Yes it is.

IS THE FLASK BPA FREE?

Yes. All YETI® Drinkware is BPA free.
