Primus Ulti 1.0 Stove

The PRIMUS Ulti Stove System 1.0 L is the highest performing and most wind-resistant gas stove, designed to deliver exceptional performance in the most extreme environments - from high-altitude summits to desert expeditions.

Despite its ultra-compact size, its powerful , innovative and reliable 3,000W burner with no blue flame effectively melts snow and boils water for 1 to 2 people. Easy to handle even with gloves, this stove boasts a low center of gravity and three sturdy feet for excellent stability on all surfaces. Simply lock the handle in the open position, place the pot with integrated heat exchanger on the burner, and you're ready to cook.

In very cold weather or when the gas cartridge pressure is low, you can turn the stove upside down for better gas flow—but always light it upright and preheat it for at least one minute before turning it upside down.

The kit includes a windproof burner with sturdy legs, a pressure regulator, and a remote cartridge hose system. It also includes a 1-liter pot with a pouring spout and integrated heat exchanger, a lid—both made of hard-anodized aluminum—and a mesh storage bag for the burner.

Gas cartridge not included — use Primus Power Gas, Summer Gas or Winter Gas models sold separately.

Always be sure to follow the operating instructions for safe handling and proper fuel supply .
