Thermos Flasks Made in The USA (3 Brands)

Thermos flasks are such ingenious inventions, but it’s not easy to find good quality ones that last. For that reason, American-made thermoses are in demand. The problem is that sometimes, the products aren’t always entirely manufactured in the USA.

So, can you still find stainless steel thermos made in the USA? I’ve done lots of research to find out if thermoses made by American manufacturers still exist. Let’s get straight to it.


Are There Any Brands Selling American-Made Thermos Flasks?

After doing some research, I found 3 brands that sell American-made thermos flasks – Liberty Bottles, Polar Bottle, and Tervis.

Liberty Bottles

Liberty Bottles is an American company founded in Washington in 2010 that manufactures water bottles made out of recycled aluminum. The company prides itself on manufacturing environmentally-sustainable products in the United States.

Its goal is to reduce the usage of plastic bottles due to their impact on the environment.

Liberty Bottles manufactures different kinds of water bottles, including thermos flasks. Liberty Bottles calls its thermos flasks insulated bottles, which is the same thing.

The company manufactures its thermos flasks in Union Gap, just outside Yakima, Washington in the United States.

Thermos Flasks Commonly Mistaken as Being Made in the USA

Sometimes, you come across companies which at first glance seem like they manufacture thermos flasks in the USA, but after doing a little research, you find out that’s not the case.

Klean Kanteen

Today, it’s owned by Jeff and Michelle Cresswell who continue to push the company forward and further lower its environmental footprint. Although Klean Kanteen thermos flasks are designed at its headquarters in Chino California, the products themselves are manufactured in China. So, Klean Kanteen doesn’t offer thermos made in America.

Tru Flask

Tru Flask is an American outdoor drinkware supplier founded in Phoenix, Arizona in the United States. It considers itself an adventure company that helps people enjoy the benefits of nature and the outdoors. Tru Flask offers insulated water bottles, among other products.

At first, the company seems to be proudly all-American. Its headquarters is located in Phoenix, Arizona, and nothing suggests its products are manufactured outside the United States. However, a quick Google search leads you to this Amazon listing, where the company confirms its thermos flasks are made in China.

Takeya USA

Takeya USA is an American company founded in California in 2008 that offers insulated stainless steel water bottles designed for sports. Takeya USA was founded by an American man and a Japanese man, taking inspiration from Japanese design but remaining truly Californian in its spirit.

At first, due to the company’s name, one might assume that its products are manufactured in the USA. However, the company is transparent and mentions on its website that its thermos flasks are made in China.

Hydro Cell

Hydro Cell is an American company founded in Idaho, USA. It’s difficult to find much information about the company online. Its website is, which might make you think that it’s an American company that manufactures its products in the United States.

However, this company is also transparent about where it manufactures its products. On its website’s FAQ section, it mentions that while its thermos flasks are designed in the USA, production takes place in China. So, Hydro Cell doesn’t offer any coffee thermos made in the USA.
