A patented mechanism locks a 100g gas cartridge (sold separately) to the anodized aluminum pot in order to make it sturdier and more stable so you can cook over precarious terrain more easily; it also features a foot support for even more stability on uneven surfaces. You can also suspend it from the trees with the safety strap on the heat-resistant case. The lid cuts cooking time significantly and keeps all the parts together during travel, and it doubles as a mug so you don't have to bring more gear than you need.17-fluid ounce anodized aluminum pot, Heat-resistant case with safety strap. 13.8oz
