MSR ISOPRO Fuel Canister

MSR ISOPRO Fuel is a screw‑threaded canister fuel for backpacking and mountaineering stoves. It is aimed at users who need consistent output and improved cold‑temperature performance.

Benefits

• Formulated blend for better cold‑temperature performance, maintaining more stable pressure in cool conditions.
• Approximately 80% isobutane and 20% propane for fast, efficient burn and good heat output.
• High‑purity isobutane with 5% or less n‑butane (manufacturer stated) for repeatable performance.
• Screw‑threaded canister compatible with standard portable canister stoves for simple, secure attachment.

Typical use: year‑round backpacking, hiking and alpine use; particularly useful in colder environments and at higher elevations where other fuel blends may lose efficiency.
