Trangia Gas Burner Primus

Verdict

We’ve loved the Reactor system—which integrates a burner, pot, and heat exchanger for superfast and efficient performance—since it won our 2007 Editors’ Choice Award. This new 1-liter version is ideal for solo hikers. I used it on a nine-day, 200-mile hike along the Pacific Crest Trail and burned through only half an 8-ounce canister (cooking breakfast and dinner for one). Boil times averaged less than two minutes in temps down to 30°F. The puck-shaped burner nestles securely into the tall aluminum pot. The stove burns ultrahot (there’s virtually no simmer) and the pot lacks a nonstick coating, so it’s best for boiling water or heating up simple meals like ramen. $170; 14.5 oz.; msrgear.com
