The Trangia principle is simple but incredibly effective. The pan is held at the optimum distance over the spirit burner inside a windshield. The windshield protects the burner from the wind but ensures it is well ventilated. All of the heat is directed upwards to the pan so little energy is wasted.The Trangia Storm Cooker became popular because of its principal advantages over the alternatives :Works at any temperature and in any weather. In fact, unlike the alternatives, it works well in windy conditions. You can turn the windshield into the wind to increase heat output of the burner.Compact. All of the Storm Cooker Systems and their pans pack neatly into a compact unit.You don't have to be an expert mechanic to maintain it. There are no moving parts to break, no jets to clean and you don't need to pump it up to pressurise it.Safe. The stove is less prone to flares than pressure stoves, also the lower windshield makes a very stable base.Clean. Fuel vaporises quickly without leaving a dirty residue. Methylated spirit is a cleaning fluid whereas paraffin is a dirty fuel.Quick and easy to set up. In a typical backpacking situation, one person can put up the tent while another puts the kettle on. This means that you get a hot drink sooner than with a conventional stove which has to be shielded from the weather.Low running cost. When compared with pressure stoves as spares are easily and fully available and there are no jets to clean.What's included in the box?Stove2 x Ultralight Aluminium saucepans - 1.5litre and 1.75 litre capacity1 x Ultralight aluminium frypan (22cm)1 x Windshield (upper)1 x Windshield (lower)1 x Burner1 x Handle1 x Strap**Please note that we recommend that meths is the ONLY fuel that is used with a Trangia.**
