If you’re buying a soup flask then it’s because you want to be able to keep your soup hot and tasty until you’re ready to eat it. However, some flasks have inferior insulation while others will keep the soup hot all day long. Think about this and compare it to your needs; nobody wants to get to lunch time to find that their food is tepid at best. Is The Flask Leakproof?

The SHO promises to keep your food hot for 10 hours or cool for 20 and it lived up to its promise for us. For hot food, it was noticeably cooler after 10 hours but still hot enough to eat without reheating. A soup flask is indispensable when you’re on the go and want to keep your food warm and ready to eat. They’re ideal for a wealth of situations like work, school, going to the gym and outdoor activities. But it’s important to look over the features so that you find a soup flask that exactly meets your needs. The vacuum flask also has a screw-top lid with a seal that helps to stop heat from escaping from the opening. For drinks flasks, you’ll need an elongated brush that can reach the bottom, whereas for food flasks, which are shorter and have wider openings, it’s generally possible to wash it as you would a mug. There’s no inner lid or cutlery with this one, nor does it promise to keep your food warm or cold for a specific amount of time. Because of this, we decided to go with a minimum keep-warm period of 6 hours.

Where to buy an insulated food flask

At 530ml, the SHO insulated food flask was one of the bigger ones we tried but you can get an even bigger 800ml version.

The Hydro Flask insulated food jar was one of the simplest designs we tried and the 28oz (828ml) version offered some serious capacity. You can also get a smaller 20oz (591ml) version, though. There are a couple of different ways a vacuum flask can keep the contents warm and it starts with the double-layered base. Whatever it is you need from a flask, our buying guide is here to help you make a bit more sense of what you need in terms of the most essential criteria – after reading this, you should be absolutely sure which food flask is right for you. Capacity Thermos is a well known brand and that fills you with confidence right from the off. But what really sets this flask apart from the rest is how durable it is. It’s made from stainless steel just like the ValueTalks flask, which as we have learned, is really robust and designed to stand the test of time.One of the most interesting things about the soup flask is that it’s actually a great way to keep your food fresher for longer. Since the flask is sealed with a vacuum, it’s incredibly difficult for germs and bacteria to get inside. No oxygen can get in which can speed up the process of spoiling and everything stays fresh and ready to eat. What’s more, this food flask is perfect for kids. Not only does it have a pretty youthful design but it’s also got a wide opening making it easier to eat and drink from. If you’re on the go with your family then you could each have one of these without breaking the bank. The only downside we could find was that the opening was a bit more tapered compared to some of the other options, which meant cleaning up wasn’t as straightforward. We're extremely confident in our products quality & our aftercare service. Our Lifetime Guarantee which applies to every SHO product is a true representation of this faith.
