Primus Ulti Stove System 1.0

Ulti Stove System 1.0L is our most windproof and high-performance gas stove, designed to deliver outstanding performance in the harshest environments—from high-altitude mountains to desert expeditions. Despite its ultra-compact size, the powerful 3,000W burner efficiently melts snow and boils water for 1–2 people.

Makes impossible meals possible
Ulti features a reliable, innovative burner with no blue flame, meaning you can melt snow, boil water, or heat food even in the most extreme conditions. The compact stove is easy to operate while wearing gloves, and the low center of gravity and three sturdy legs ensure stability on any surface. Simply lock the handle in the open position, place the integrated heat exchanger pot on the burner, and you’re ready to cook. In extreme cold or when the gas canister pressure is low, you can invert the stove for better fuel flow—but always ignite the stove in the upright position and preheat it for at least one minute before inverting. Always follow the instructions for safe handling and proper fuel supply.

Ultra-compact all-in-one stove for expeditions
Ulti Stove System 1.0L is a compact expedition stove that includes everything you need to prepare a hot meal in any environment. The set includes a windproof burner with sturdy legs, a pressure regulator, and a remote-canister hose system. It also comes with a 1-litre pot with a spout and integrated heat exchanger, a lid—both made of hard-anodized aluminum—and a mesh storage bag for the burner. Gas is not included—purchase Primus Power Gas, Summer Gas, or Winter Gas separately.

Powerful 3,000W performance
Ulti’s innovative burner combines catalytic combustion and infrared radiation, eliminating an open flame and making it our most wind-resistant stove. The 3,000W burner boils 1 liter of water in just 3.5 minutes, with a pressure regulator ensuring consistent heat output. Always use the gas canister in the upright position. In extreme cold or low-pressure conditions, you can invert the fuel canister for improved performance but always ignite the stove in an upright position and preheat for at least one minute before inverting. Always follow the instructions for safe handling and proper fuel supply.

Get even more out of your Ulti stove
Ulti Stove System 1.0L is a complete gas stove and pot kit, but you can enhance it with the PowerLighter, which ignites in all weather conditions. For larger meals, add the Ulti Pot 1.7L for 2–3 people or the Ulti Pot 2.5L for 2–5 people.
