Trangia - Duossal 25 Casserole 1.75L is, with the duossal material, an upgrade of the classic Trangia Pot. The Duossal material is a combination of aluminum and steel, which is a perfect combination for a solid Pot. Aluminum gives the pot heat-conducting properties, which means that with the burner you get an even heat. The steel on the inside makes it possible for your Pot to withstand a tougher treatment without damaging the coating. At the same time, the sewing needle does not release any harmful substances into your food. This Pot is difficult to dent or deform, due to the perfect combination in the form of duosal.
