My Caldera Cone ti Sidewinder in ESBIT mode or Inferno wood burning mode. It fits inside my matching 3 cup hard anodized aluminum pot or in my pack's side pocket.
This CC version is very efficient for burning wood due to its double wall Inferno conversion. In areas where wood burning is prohibited I use the even lighter ESBIT Gram Cracker setup. I've found it to be at least 40% more efficient than my previous Vargo Tri Ti ESBIT stove & windscreen in terms of fuel consumption.
