alfi insulated drink bottle isoBottle Active Bike, steel 0.35L (household goods)
Very good insulation, the tea was even after 2 hrs. Still hot as hell, but outside it is warm to the touch. This bottle is just not as much in it (only 0,35 l), goes just some of the insulation on it, then better the larger (0.5 l) take for 3 euros m
