The new Optimus Vega is a high performing lightweight remote canister stove with integrated 4 season mode. It offers two ways of cooking in one stove. When cooking in cold temperatures or when extra fast boil times are needed, just open the gas canister support legs and turn your gas canister upside down and continue cooking in the 4 Season Mode. For excellent efficiency and precision cooking on a low flame use the Efficiency Mode. The Optimus Vega has the lowest profile in its category. This means superiour stability, especially for larger pots. The included windscreen with rounded corners easily adjusts to two sizes.
