Replacement or spare Inner saucepan for the The Trangia Ultra Light Aluminium Series 25 (code T25/1UL). Trangia aluminium stove systems spread heat quickly and evenly. This means that food does not, for example, burn and stick to the centre of the frying pan. In addition, the hard surface means that the systems are very resistant to scratching and wear. Ultralight aluminium is 50 % stronger than ordinary aluminium.
