Best Insulated Food Containers, Water Bottles, Mugs, and Flasks (2021 Edition)

Thanks to technology we now have insulated food containers, water bottles, mugs and flasks that can keep our colds cold, and our hots hot for longer than ever. Below is a selection from each of these categories that offer conveniences we’ve grown to love deeply.

These days, it’s hard to imagine a hiker or camper heading to the outdoors without an insulated bottle for cold water or hot drinks. That’s why we’ve rounded up some of the best insulated mugs, bottles, flasks, and food jars in 2020. And although the insulated bottle’s popularity has surged in recent years with new brands and technology entering the market, it’s actually a pretty old idea. In fact, it was first invented in 1892!

A few years later in 1904, two Scottish businessmen came up with a vacuum sealed bottle that could be used by the general public. They called it a “thermos” (from the Greek word for “heat”), and it later became the very first product of The American Thermos Bottle Company (known as Thermos today). Other brands and designs soon followed and the insulated bottle became a must-have for anyone spending extended time in the outdoors.

This simple, low-tech design has stood the test of time and it’s still your best option for keeping drinks and food hot or cold. (Especially if you plan on fall or winter camping.) Here are some of our favorites for crisp fall evenings and hot summer days.

Insulated Mugs

Sometimes you just need a mug that keeps your coffee hot but doesn’t do much else. The following options won’t hold a lot and don’t fit in car cup holders, but they’re great to have for mornings at a campsite. (Or at work!)
