Trangia 25-1 Ultralight Duossal Gas Burner

Lightweight backpackers and minimalist campers demand cooking systems that won't weigh them down without sacrificing performance or reliability. The Trangia 25-1 Ultralight Duossal Gas Burner represents a breakthrough in compact stove design, engineered for those who refuse to compromise between pack weight and cooking capability. This Swedish-engineered system delivers efficient heat output in an ultra-compact footprint, making it the go-to choice for alpine expeditions, bikepacking adventures, and extended wilderness trips where every gram matters.

• Dual-fuel compatible design operates on butane, propane, and isobutane cartridges for global versatility
• Integrated wind protection and heat reflector maximizes fuel efficiency in exposed mountain conditions
• Tool-free assembly and disassembly allows quick setup and pack-down in harsh weather
• Sealed burner head prevents moisture infiltration and extends cartridge lifespan during wet expeditions
• Compatible with standard 25mm pot diameter cookware, offering flexibility in selecting ultralight cooksets
• Simmer control valve enables precise flame adjustment from high-output boiling to gentle simmering
• Integrated piezo ignition eliminates need for matches or lighters in damp field conditions

In real-world backcountry conditions, the Trangia 25-1 excels where traditional liquid-fuel stoves struggle. The burner achieves near-instant ignition in sub-zero temperatures thanks to its optimized cartridge cradle design that maintains ideal pressure even when fuel is cold. Experienced mountaineers praise its ability to boil water for hot meals and beverages within minutes, critical for morale during extended alpine camps. The low center of gravity and compact footprint prevent tip-overs on uneven ground, while the refined heat output reduces fuel consumption compared to earlier models—a significant advantage on month-long expeditions where resupply options are nonexistent. Users consistently report 90+ minute burn times per cartridge under typical backpacking cooking loads, making fuel planning straightforward and predictable.

This system is purpose-built for ultralight hiking enthusiasts, fastpacking adventurers, and mountaineers who understand that ounces equal miles. Whether you're attempting a challenging alpine traverse, embarking on a self-supported ski touring expedition, or simply seeking the absolute lightest cooking solution for multiday treks, the Trangia 25-1 Ultralight Duossal Gas Burner delivers Swedish engineering excellence in a package that barely registers on your scales while reliably delivering hot meals wherever your adventures lead.
