The 4-Season Gas by Optimus keeps outdoor stoves running perfectly in all seasons. The high-quality gas mix consists of propane, butane, and an increased amount of isobutane, which features a particularly low boiling point. As a result, the 4-Season Gas delivers the same stable performance at near-freezing temperatures and high altitudes that users expect in milder conditions.

The dark gray color of the canister has a warming effect on the gas when exposed to sunlight an serves as camouflage at night. The smart seal protects the contents and indicates whether the canister is new or previously opened.

Contents: 70% isobutane, 25% propane, 5% butane
