When it's time to cook for your family while on your outdoor adventures, the Solo Stove Campfire is the ideal choice for you. The portable campfire pit is made from durable 304 stainless-steel and uses sticks, twigs, pine cones or biomass as its fuel. Designed with a heat shield between the ash pan and the bottom of the stove that protects the ground under the stove from scorching. Its cooking ring's angled lip increases efficiency by strategically directing the heat towards your pot to help reduce heat loss. How It WorksThe air intake holes on the bottom of the stove channels air to the bottom of the fire while at the same time it channels warm air up between the walls of the stove. Secondary combustion is caused when the preheated oxygen is fed back into the firebox through the smaller holes on the top which ensures less smoke is produced. Runs on sticks, twigs, pine cones & other biomass Environmentally friendly Manufacture's lifetime guarantee
