For maximum efficiency and minimum consumption, use our high-performance propane / isobutane four-season blend. Propane provides higher vapor pressure for better performance in cold weather. Isobutane provides more constant pressure as the fuel level gets low. Available in both 100 gram and 230 gram canister sizes.
• 230g canisters will pack inside of the Sumo Companion cups and the Sumo systems.
*Fuel cannot be shipped - Available in-store pickup only*
