Trangia’s unique Duossal 2.0™ super laminate consists of aluminum and stainless steel pressed together under high pressure. It is an optimal combination where the aluminum exterior provides excellent heat conductivity, while the stainless steel interior makes the cookware scratch-resistant and easy to clean. The material thickness is 0.8 mm, with 0.3 mm being stainless steel. This provides sturdy vessels for real outdoor cooking.
