The Primus PrimeTech Insulation Bag is the accessory that unlocks real multi-course cooking on a single stove. Designed as a companion to the PrimeTech Stove Set and Essential Stove Set, it lets you bring one pot of food to temperature, transfer it to the insulation bag to finish cooking and stay warm, then free up the stove for the next dish. The result: hot, properly cooked meals with less fuel, less waiting, and no juggling act. Available in 1.3L and 2.3L to match both pots in the PrimeTech system.

Cook Two Dishes at Once — On One Stove

The PrimeTech Insulation Bag solves one of the fundamental constraints of backcountry cooking: you only have one heat source, but you want to eat more than one thing at the same time. The workflow is simple — bring your rice, pasta, or stew to a boil in one pot, transfer it to the insulation bag to retain heat and finish cooking through residual warmth, then use the freed-up stove to fry vegetables, simmer a sauce, or boil water in the other pot. Both dishes are ready at the same time, both are hot, and you've used less gas than running two burners.

Thermal Retention That Works

The insulation bag is designed to hold heat long enough for food to finish cooking and stay meal-ready. Once a pot of food is brought to the appropriate temperature on the stove, the bag's insulating construction traps that heat and continues the cooking process — similar in principle to a thermal cooker, but in a compact, packable form sized for backcountry use. It's particularly effective for dishes that benefit from longer, lower-heat cooking: rice, grains, legumes, and one-pot stews that usually require extended simmering over a flame.

Sized for the PrimeTech and Essential Stove Set Pots

The insulation bag is available in two sizes to match the two pots in the PrimeTech cooking system. The 1.3L bag fits the smaller pot and is ideal for soups, sides, and individual portions. The 2.3L bag accommodates the larger pot for full main courses and larger group servings. Both sizes are designed to fit their respective pots securely, ensuring effective heat retention rather than a loose fit that lets warmth escape.

Save Fuel, Reduce Boil Time

Beyond the multi-dish convenience, the insulation bag is a genuine fuel-saving tool. By finishing cooking in the bag rather than keeping a flame burning under a simmering pot, you reduce total gas consumption per meal — meaningful on multi-day trips where canister weight and longevity matter. It also reduces the amount of active stove time required, which means faster camp setup and more time eating instead of cooking.
