The SOTO WindMaster with 4Flex is one of the most efficient and wind-resistant backpacking stoves on the market—engineered to perform in harsh conditions where lesser stoves struggle. With its micro regulator valve system, built-in windscreen effect, and lightning-fast boil times even in gusty weather, the WindMaster delivers consistent cooking power without added bulk. Whether you're melting snow at altitude or boiling water at a breezy basecamp, this stove is a trusted companion for serious adventurers.

The concave burner head and close pot-to-flame design function as an integrated windscreen, shielding your flame from wind and increasing fuel efficiency. Paired with the 4Flex pot support, it accommodates larger cookware, while an optional TriFlex support (sold separately) allows for minimalist setups with smaller pots. The stealth igniter improves durability and reliability while reducing weight.

Features

• Unmatched Wind Performance: Concave burner design and close pot positioning act as a built-in windscreen, protecting the flame and improving boil times in gusty weather.

• Fast Boil Time: Boils 2 cups of water in under 2.5 minutes—even in strong wind.

• 4Flex Pot Support: Wide and stable, supports larger pots for group meals or gourmet backcountry cooking. Compatible with optional TriFlex support (sold separately) for smaller pots.
