The Chill/Heat Factor—Insulation

This is an immensely crucial factor regardless if you’re planning on keeping hot or cold liquids or food in your thermos.

This results in thermoses that offer optimal temperature control and retention. Put simply, if you want better temperature control, opt for an insulated thermos.

The Size

Generally speaking, thermos sizes range from 10-ounce containers to 2-gallon containers. Take note though that to contain the same amount of fluid inside, the thermos should be larger if it has a double-wall construction.

The Bottom Line

In this day and age, you really can’t afford not to have at least one handy thermos on hand. Aside from keeping your beverages or food warm during the cold season, it could likewise keep your food and drinks cold during the hot summer months.

With so many options to choose from, however, you can refer to our list above to help you out. Whether you need a thermos for working out, hiking, camping, or for daily use, there’s a perfect one out there for you.
