I like a brew on the move and I've owned my fair share of thermal mugs but to be honest I've never found the perfect one.
I'm after something that will fit in the standard sized cup holder of the car.
The lifeventure ones are good but they can leak and you have to unscrew the lid to drink, not good when driving. Others have leaked and start to get a bit clogged up with dry tea and gunge around the sliding opening on the lid.
Maybe I'm being fussy but there has to be that perfect one that works out there?
