Product Information

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 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.

Some flasks are also designed with the intention of maintaining a low temperature for cold food. While not fully refrigerating them, flasks designed for this purpose will usually keep things cold longer than they keep things hot. But, some flasks are not meant for this, so bear that in mind. You get a foldable spoon with this food flask, which is stored on top of the inner lid. The inner lid also features a secret compartment just below the spoon, which can be used for storing salt and pepper if needed. Best for big meals – SHO’s Ultimate Food Flask is not the biggest flask out there, but it is bigger than most. 2 sizes are available for the Ultimate, both of which are bigger than comparable flasks. The smaller is 600ml, which beats out other similarly sized flasks which are usually around 500ml, and the 800ml compares with others usually around 700ml. So unquestionably, if you’ve got a big appetite (or are carrying food for two) then the Ultimate should be your flask of choice. An honourable mention does go out to Pioneer’s 1000ml food flask, however.

What to look for in an insulated food flask

The leak-proof design also promises to keep your food hot for up to six hours or cold for up to eight. Sandwiched between the inner and outer layers is a void - this vacuum stops the heat from the inner layer reaching the outer layer as heat can only be conducted through particles, whether it’s in the air, through liquids or solids. Finally, think about how easy it is to clean. Some flasks are dishwasher safe but it’s almost always better to wash it by hand. For this reason, a flask with a wider opening is generally better.

When we tested this flask, it kept the contents piping hot until we were ready to enjoy it and the slimline frame meant it was easy to store in our lunch bags or take on the go. You can also get larger ones of over 800ml, which might suit one very hungry person or a lighter lunch for two.

The ones that will keep your food warm for longer will generally cost more, but they can also be more versatile. The one thing that this jar does have going for it is its extra wide opening, which makes adding food in and washing up afterwards that much easier. It has a 400ml capacity, which is perfect for one person - although if you’re particularly hungry you’ll need some extra sides.
