Who can recommend the best flask and accompanying cups for nice tea on country walks? I've tried a couple so far but they all end up tasting of metallic or plasticy hot water, made even worse by manky cups.
We're going out a lot with the kids to places without cafes or similar takeaways and with the colder weather we'd quite like to enjoy a nice cup of tea... (Ponders 20s self looking at this post and wondering where the exciting life plans had got to)
