Optimus

4-Season Gas

<p>The 4-Season Gas from Optimus is, as the name suggests, ready for use all year round. Its successful gas mix made from isobutane (70%), propane (25%) and butane (5%) has a particularly low boiling point - so excellent burning performance is guaranteed even at temperatures around freezing point. The grey colour of the cartridge additionally warms the gas when exposed to sunlight, providing even more power.</p> <p
