Newfoundland Coffee Company Viking Tumbler

Thanks to the double-wall construction and internal copper lining, this tumbler is designed to maintain your beverage's temperature for several hours. While exact times vary based on ambient temperature and how often you open the lid, it is built to keep drinks hot or cold throughout a standard workday.

The lid features a press-in, twist-closure mechanism with a vacuum seal designed to prevent spills during transit. While it is highly secure for daily commutes, we recommend keeping it upright in your bag rather than tossing it in loose to be safe.

No, this tumbler is not dishwasher safe. To preserve the integrity of the vacuum seal and the exterior finish, we recommend hand washing it with warm, soapy water.

The copper lining acts as an additional thermal barrier inside the double-wall construction. It significantly enhances the vessel's ability to retain heat or cold, outperforming standard stainless steel tumblers that lack this extra layer.

Yes, with a 20-ounce capacity, the Signature Viking Tumbler is designed with a tapered base that fits comfortably in most standard vehicle cup holders.
