Drobot Dean via Adobe StockNo matter where you are, it comes in handy to have a portable flask and a couple of cups to take a break and sip your favorite drink.

To help you in your search, we put together a list of the best travel flasks. We’ll also address the main things to keep an eye out for when choosing a proper travel flask.

Things To Consider in a Travel Flask

When deciding on the best travel flask to purchase, you should consider the appearance, capacity, and several other important determining factors. We’ll go through all of these in detail, so you can feel fully prepared to make this purchase.

Flask Size

The best travel flask should fit into the palm of your hand and be compact enough so that you can carry it along on your next trip. You don’t need exact mug-sized flasks, as these are rather temporary solutions so you can enjoy your favorite drink while traveling or on the go.

Bottom Line: A proper travel flask should be no longer than 4 inches and as small as 2 inches wide for a perfect fit, although there are slight variations to these measurements.

Capacity

Let’s face it — you will mostly be wondering about the capacity of your new travel flask. Some travel flasks fit around 8 ounces, allowing you to fill at least a couple of small cups. Some options come with a set of properly-sized cups, so you won’t have to bother looking for those as well.

Materials

Perhaps the absolute favorite of many travelers is a stainless-steel flask certified to be chemical-free, keeping your drink nice and cold. Unfortunately, there are not many flask material variations available, so a steel option is an obvious choice.

However, some plastic flasks are also certified chemical-free, so you won’t have to worry about any allergic reactions or negative side effects on your health.

Lid

If you often have your hands full, you may want to consider a flask with a flip-lid. This stays attached to the flask while you drink, so you’ll never drop the lid accidently. You’ll also want to look for a flask with a secure seal and screw top to avoid it leaking in your bag or pocket.

Pattern and Looks

Now that we’ve covered most of the practical features, it’s time to debate the appearance of your flask. Some of you will prefer traditional steel flasks that resemble the ones from Wild West movies. Others will want to look for simple styles without being too flashy.

There’s something for every traveler when it comes to travel flasks, so it really comes down to personal preference.
