The Kelly Type Kettle in Hard Anodized Aluminium i.e. the Ghillie Adventurer which can boil 1.4 Litres in a similar time to a high power gas stove really isn't to heavy for backpacking. i.e. The Kettle with cooking pots etc weighs around 1200 grams.

Even a lightweight gas stove with a 450 gram cartridge will weigh around 750 grams. Add a Titanium Pot of a similar capacity will weigh around 140gms. 890 grams. With a 450 gram cartridge you can typically boil around 30-35 litres, with a windscreen, such as a titanium foil one @ 70grams you are now @ 960 grams.

The Kelly type kettle can also double up as a water sterilization device and as a water bottle so you can leave that 300 gram water filter and that 140 gram stainless steel water bottle behind as well. If fuel is easily available i.e. small twigs, feathered sticks, pine cones are readily available the Kelly type kettle would be very useful for wilderness trips greater than 7-10+ days. i.e. a longer term bug out situations let alone for home emergency and vehicle or even bicycle adventuring.
