Can I use the Flask for food?

All Rambler® Products are food-safe and BPA free, but the Flask is not made for food.

Is the Flask lead free?

All YETI® Rambler® Drinkware is Lead Safe. The strictest lead restriction applicable to YETI's stainless-steel Rambler® Drinkware is the Extractable (Leachable)

21 Elements that includes all heavy metals of concern along with lead for Metals and Alloys in Food Contact Material and Articles.

Is the flask double-wall vacuum insulated?

Not quite, it’s single-wall stainless steel so it’s lighter and easier to carry.

Will the funnel be available for purchase separately?

No.

Are there any tips for maximising temperature retention?

This is a single-wall stainless steel flask. Stainless steel is conductive and will not retain temperatures like our standard Rambler® Drinkware line which is vacuum-insulated. If you’re needing thermal retention, check out our Rambler® Drinkware on yeti.com

How do I get the smell out of my Flask?

Since it’s Dishwasher Safe go ahead and wash it there. Make sure to wash before initial use. Remove the cap from the Flask and place cap and funnel in the utensil basket in the dishwasher. Place Flask on the top rack of the dishwasher. For more thorough cleaning, fill the Flask with warm soapy water, close it with the cap, and shake. Rinse out with water before drying.

You can give it a chill in the Beverage Bucket.
