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!
Value for money
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.
