Description
Half a litre, a steel cup that unscrews from the top, and a stopper you can pour through without taking off. It holds above 70 °C for twelve hours, which is long enough for a pre-dawn start and a second cup at the summit. The body is 0.6 mm steel — heavier than it needs to be, so it survives being wedged into a pack against a stove. Every part of the stopper comes apart for cleaning, and we stock replacements.
