Great little mug

Keeps your coffee warm during walks and hikes.

Small and compact

Great for drinking tea as there is a filter inside. Kinda hoped for a bigger bottle.

Good quality for a good price!

I wanted to get a flask to use in work but didn't want to spend a fortune on one, however I've found other cheap ones do not keep my brew as hot for as long as I needed. Bought this when in store on a whim and was surprised to discover it would keep my brew hot for up to 6 hours. It's looking a little battered as I have a habit of dropping things but it doesn't leak and does the job. Would highly recommend and would buy again!

Best buy

Great mug. Keeps liquids hot for a long time. I bought the black one and this red one was for my son. Great value.

a brand you can trust

The flask keeps water hot for many hours. It looks attractive and very handy. The downside is there are not a lot of sizes or colour you can choose.

A great (slightly over) mug sized thermal cup!

This thermal mug holds slightly over a standard sized mug of hot drink. If you warm it before use, as you would with any thermal cup, it will keep your hot drinks hot from morning until afternoon. The teabag holder/ coffee strainer is an interesting feature that I have yet to try out but it also seems to stop any splashes that usually jump out if you drink whilst walking. I haven't tried it with cold drinks yet but I have no doubt it will perform equally as good! The size of it is roughly the same as a 500ml bottle of water so it fits into the side pocket of most back packs / day sacks. As it's available in different colours I might just have to get another one!

So good I bought two

This is great for taking coffee to work or on a shorter walk. Does not stay hot as long as a traditional flask but is fine for travelling or shorter walks. I take mine every day to work in my bike pannier or rucksack. Nice to drink from and robust. Great value - much cheaper than other brands.

leaks with in a week

I used the mug and was very happy because it keeps the tea hot and no taste changes. But after using for four days now there is leaks of tea and can't even drink from it because of leak. But will give one more try by replacing it.

Not as good as a thermos

Had some tea out of one of these after walking for 3 hours in freezing temperatures. It was warm but by no means hot. My friend had a proper thermos which still had steam coming off it.

Hi, I am sorry to hear that you had issues with the Isothermal 0.4L Mug flask. I am not sure if you aware but before you put your hot drink in, you should put a couple of inches of boiling water in the bottom and leave it for a few minutes. Once it has been a few minutes, you then tip out the water and put your hot drink in.

If you have tried this and you still have the same issue, then please return it to your local store so then they can arrange an exhange or refund for you.

Perfect product

It is a perfect size, can take it anywhere and it also fits wherever I want to put it :) and works just perfect, never leeks and keeps the drink warm for very long time. For me this is "how we do it" !;))

Good product.

I am impressed with these lil things, quality product.

Advice to optimize the performance of your isothermal bottle.

Fill the mug with boiling water for 5 minutes. Then replace the water with your beverage. Close the mug. The fuller the mug, the better it is at keeping the contents hot or cold.


The lower part of the lid holds herbal tea bags, tea leaves or other. This strainer is removable. The wide opening and the surrounding plastic allow you to drink quickly and directly, placing your lips on the mug without getting burned.
