The Zippo OUL incorporates dual flame technology to produce an extra strong flame - actually two flames. The primary blue flame is an oxygenated fuel mix, while the secondary yellow flame burns directly on fuel. The flames meld together to create a robust fire, even in harsh wind conditions.
The OUL features a water-resistant cap, rugged metal construction and built-in LED light. Also included is a patented child-resistant safety button, a fuel level indicator for the refillable butane tank, an adjustable flame dial and a rugged carabiner clip with strap.
