Got a trangia 25 stove? get this kettle! - Trangia Aluminum Kettle

This kettle is great - nestles down inside the stove when packed and holds your stove and handle. I recommend using a ziploc-type freezer bag to protect the inside of your kettle from scratches and fuel.
Because the kettle sits down close to the burner and inside the windscreen, the heat surrounds the kettle and heats water quickly. I usually can get 2-3 good kettlefulls boiling off one fueling of the burner.
If you manage to melt the knob on the top of the kettle by heating it over an open fire, head down to your local hardware store and find a small metal drawer pull to replace it. Check the package before you go home - unless the included bolt has break-away sections, it will be too long to work. Get a shorter bolt, use a dab of thread-locker or glue on the threads, and you'll all set!
