The major features of the Express Spider are its simplicity and clean design, lightness of weight, and the pre-heating tube. This tube is so important for cold weather use since it ensures that the LPgas is in a truly gaseous state by the time it reaches the burner. LPgas stoves without a pre-heating tube struggle to perform well in wintry conditions.
The burner itself is the same as the Swedes use for their very successful ExpressStove [which is mounted directly onto the cartridge and has been tested and proven many thousands of times]. It delivers high efficiency, which can be further improved by using Primus' unique EtaPower pots. The gas cartridge is connected with a rugged steel flex hose, also a well-proven Primus component. Combined with its strong feet and non-slip potholders, this will be a fits-all stove with a broad range of applications. The ExpressSpider is probably the lightest remote gas cartridge stove on the market with a pre-heater tube. Stable, rugged, small pack size, and with Primus quality it is available from the beginning of 2010.
Output: 7150 BTU/h
Size: 4.7" x 3.3" x 2.2"

When the patent had expired and other manufacturers could begin to compete with their own kerosene stoves, they found they had to put up with people referring to their stoves as Primus stoves, too.
After more than a month of trekking and climbing, hauling ten tons of equipment over countless crevasses and across the unexplored, thousand meter high Khumbu Icefall, the expedition set up top camp, one hundred meters below the razor summit of Mount Everest, the world's highest mountain. The British expedition under the leadership of John Hunt had steadily fought its way closer to the peak. Each day had been a struggle against the harsh and unpredictable elements. Now its members could actually see the summit, so close yet so far away.
A New Zealander, Sir Edmund Hillary, and a Sherpa, Tenzing Norgay from Nepal, were given the honour of trying to make the top. But they had to break off their first attempt because they simply did not have the strength to make it all the way. Once they had rested up for a couple of days, it was time to try again. It was clear and sunny and it seemed as though they were going to make it. But the weather suddenly changed to a lashing storm that made it impossible to see the attempt through.
Throughout the entire expedition its members had cooked food, made tea, boiled water and lit up the dark nights with Primus stoves and lanterns that worked without problem, regardless of winds or temperatures.
