Collapsible mugs (no, not me:) A bit like a concertina, folds flat when not in use. Stable ie you can put it down and not worry about it collapsing. It insulated fairly well in that you can pick it up when it's full of hot liquids. The flexible silicone doesn't taint the contents with any unpleasant tastes. Very useful when you want to take your own drinks container, which doesn't take up any space in rucksack/luggage. Fairly robust. My oldest one is about three years old. However, I did stand on my other one whilst wearing crampons and I can report it now has holes in it:)
