At Primus the letters "EX" stand for expedition suitability. And that is exactly where the new TrailBreak EX Vacuum Bottles feel at home. Apart from keeping drinks hot – or cold if needed – they are really rugged, easy to handle (also with gloves at very low temperatures), you can clean them easily and – best of all – drink directly from the bottle and. In addition, they simply look good while being available in four colours and in two sizes.
Perhaps we need a vacuum flask test article, where temperatures are data-logged over time for a selection of flasks that are on offer at the moment. I'd like to know which one is best for insulation too.
