The 3" Titanium Folding Firebox Gen2 Nano Ultralight Backpacking Stove (patent pending) Just got better, We've added position points for the new Nano Sticks (included with stove purchase) this makes the Gen2 Nano perfectly adapted to Trangia Spirit Burner use. Allowing a full range of Simmer Ring adjustment and three head space settings. The Gen2 Nano also accepts the Trangia Gas burner attachment. The Nano Sticks nest into the folded Nano in such a way that they cannot fall out. At only 4 ounces, the Titanium Firebox Nano is 3" wide and folds down to a ridiculously thin .25". With its proprietary cross-feed fuel delivery system, this Nano stove can bring 2 cups of water to a boil in 3:10 minutes. Even with all this power, the Firebox Nano is one of the smallest wood burning stoves on the market. Like its big brother, the Firebox Nano is hinged and requires no assembly.
