The 25 series includes the larger models, which are suitable for groups of 3-4 people. These excellent family sets consist of larger cookware and a wider frying pan. With the holders folded up, the cooker can be used with larger pots from the Trangia range. AluminiumAluminium is a lightweight material characterised by fast and even heat distribution. This avoids burning in the middle of the frying pan. The hard surface also offers good protection against scratches and wear. Ultralight aluminium is 50% stronger than conventional aluminium. This means that a smaller amount of the material is required during production, which makes the storm stoves lighter.
