Sorry to barge in, but this seems the best place to ask. I'm looking for a good but not too expensive thermal flask to take water to work. This is because I work outside and in England most of the year it's freezing cold, so I end up not drinking any water during the day because it hurts my teeth. I was thinking about something like pic related.
