Primus developed their Winter Gas to increase the performance of gas stoves at lower temperatures. Low temperatures reduce the pressure in the gas tank and worsen the evaporation of the liquid gas. This causes the stove to burn with less power or not at all, even though there may be gas left in the container. The main innovation behind the improved cold weather performance of Primus Winter Gas is VaporMesh. VaporMesh is a highly absorbent paper that sits around the entire inside of the container, thus increasing the surface area from which the liquid fuel evaporates to gaseous form. This helps keep the pressure higher which makes the stove burn better. The widened surface area also speeds up the liquid to gas transformation process, and it is this rapid transformation that determines the pressure inside the container. Fast process = high pressure.Compared to conventional gas containers, this is what gives Winter Gas its reliable performance, even in cold conditions where it was previously impossible to use gas.Smoother performance:This is how Winter Gas maintains a smoother performance.1. Expanded surface area = increased pressure:The phase transition takes place from both paper and surface instead of only the surface of the container as with a conventional gas container. In this way, the surface area is expanded without requiring a larger container. This increases the pressure in the gas tank.2. Reduced boiling time:The VaporMesh paper and gas mixture increases the speed of the phase transition from liquid to gas. The burner receives more fuel, which means that the cooking time in really low temperatures will be shorter compared to other gas containers.3. VaporMesh™:A type of paper that coats the inside of the container and absorbs the gas in its liquid form. The effect of the VaporMesh paper intensifies as the fuel level decreases, and the gas gets a smoother performance over the lifespan of the gas tank.4. Liquid gas:The mixture of propane and isobutane gas is the same as that of Power Gas: around 20% propane and 80% isobutane.
Bird Brand Methylated Spirit is a general purpose alcohol for use as a stove fuel, cleaner and and thinner of French polish.
Threaded cartridge of premium mix butane, propane and iso-butane for use at low temperatures.
Primus Power Gas is their most multipurpose and potent mixture, delivering excellent power from spring to winter. Even if the temperature drops below freezing it stills provides significant pressure to keep a stove running. Its versatility makes it suitable for situations where the weather and temperature conditions are uncertain. Available in 450g.
The Trangia Fuel Bottle with Safety Valve is an essential for the safe storing and transporting of flammable fuels to be used with your Trangia cook set. Available in 0.3, 0.5 and 1.0L sizes, the unique design of the safety cap on these bottles allows you to pour the liquid without removing the cap. The cork has a venting spout and a pouring spout that allows the liquid to flow smoothly, reducing the chance of spills. Tested by TÜV to meet international standards.
The Primus Fuel Bottle is a very lightweight fuel bottle designed with aluminium and lacquered to provide better protection and durability. Suitable for OmniFuel, MultiFuel, VariFuel, Gravity VF MF and EtaPower MF as well as most commonpump stoves that burn liquid fuels. The bottle does not come with fuel.
This compact and lightweight backpacking stove system can feed 1-2 and offers the most efficient heating in an easy to use and easy to pack footprint. Attach and lock the 0.5L pot to the burner with a simple twist. The Piezo igniter lights the stove with a push of a button so you can boil water quickly.
The Primus PrimeTech Stove Set is fuel efficient all-in-one stove system that's suitable for cooking for multiple people. This stove set is perfect for the backpacking chef, offering the most stable and windproof burner whilst providing the consistent power that's needed for a rolling boil, a slow simmer and everything in between.

Primus Summer Gas is a mixture of propane and butane and is optimised for summer conditions with temperatures between 15 °C and 40 °C. At really hot temperatures, other gas mixtures may be too powerful, meaning reduced efficiency and increased fuel consumption. There is no such risk with this gas mixture.
