Okay guys, I need help! I've been drinking coffee nearly every morning on the train, which is becoming a really expensive habit. So I decided it's time to buy a decent travel mug. I have one of those Brugo mugs, but it doesn't keep my coffee warm for very long, and it usually spills any leftover in my bag
So I need something spill-free, that I can put in my back while I'm cycling to the station without worry. Does anyone here have a recommendation?
