Needs to be thermal (keeping coffee at a decent temperature for a couple or three hours) cos I make it before I leave home and then take it to work - my pretty simple Senseo one worked well in the summer, but it's now too cold for it to stay warm
Doesn't matter if it won't fit in a cup holder as I don't drive many vehicles with those - so it's almost preferable to have a wide ish base, just not too tall (I'm only putting a small mug of coffee in it, not a bucket full!!), I have to drive so it doesn't fall over; this works till the cup is empty but then I can put it back in my bag!!
I've currently got this which is totally big enough at 350ml (could probably manage with 300 or 250ml - but would need to measure when I make coffee in the morning!!). It is only plastic and not very thick so whilst good for hot drinks in summer, definitely no good in a cold bus in winter in the Alps!!!

Found this (doesn't have to be pink!) which looks like it 'might' have a flip up bit to make it sippy?
