MSR IsoPro Fuel Canister
MSR IsoPro is positioned as the go-to canister for cold-weather performance thanks to an isobutane/propane blend engineered to vaporize reliably at lower temperatures and deliver steady boil times. It balances high technical performance with broad compatibility across canister stoves, making it a strong middle ground between premium cold-specific blends and budget mixes. Compared with niche cold formulations from Primus or Optimus, MSR often offers slightly better value-per-use for users who need dependable winter performance without paying a premium for extreme-cold specialization.

Jetboil JetPower Fuel
Jetboil JetPower is optimized for Jetboil systems and focuses on fast, efficient fuel delivery in cool-to-cold conditions, giving it an edge for users running Jetboil burners where heat-exchange efficiency matters. While it may be priced a touch higher per canister than generic mixes, the technical pairing with Jetboil stoves often reduces overall fuel consumption, offsetting the upfront cost. Compared with MSR and Primus canisters, JetPower is a specialist choice that yields real-world time-and-fuel savings for Jetboil users but is less universally efficient on other stove designs.

Review Summary
"Owners report consistent, predictable performance with Jetboil systems and decent cold resistance for cartridge fuel, but many note reduced output below freezing compared with liquid fuels. Valued for compatibility and convenience more than extreme cold reliability."

Primus Winter Gas
Primus Winter Gas is formulated specifically for sub-freezing conditions, typically containing a higher proportion of propane to maintain pressure when temperatures drop, making it the leader for extreme cold-weather reliability. Its technical advantage is predictable pressure and ignition in harsh winter use, though that real-world performance usually comes at a premium compared with standard blends like Coleman. Against MSR and Optimus, Primus is the most conservative choice for expeditions where lowest-temperature performance outweighs cost or broad stove compatibility.

Coleman Max Propane/Butane Mix
Coleman Max Propane/Butane Mix is the budget-minded, widely available option that gives solid performance in cool conditions and excellent value for casual winter campers and mixed-season use. It sacrifices some low-temperature vapor pressure compared with winter-optimized canisters, so it’s best for near-freezing rather than extreme sub-zero use, but its low price and ubiquitous retail availability make it financially attractive. Compared to the specialist performance of Primus or Optimus, Coleman is the pragmatic choice for users prioritizing cost and convenience over best-in-class cold performance.
