The SOTO WindMaster Stove with 4Flex is an ultralight gas stove with a micro regulator and a wind-resistant concave burner, weighing around 67g on its own. It's the stove for cold mornings, high camps and anywhere a normal canister stove starts to splutter. The micro regulator is what sets it apart: it keeps output consistent as the canister cools and as altitude rises, so boil times don't fall off a cliff at the end of a cold trip. The concave burner head gives real wind resistance without a bulky windshield, which means faster boils and less gas used in exposed spots. Ignition is manual by design; SOTO leave out the piezo for maximum reliability, so carry a lighter. This version comes with the 4Flex pot support, a wider base that steadies larger pots and group cooking while still folding down compact. Total weight with the 4Flex is about 87g. Choose the WindMaster when you want a serious fast-and-light stove that won't let you down when the weather turns.
