This meta-71 is tiny and folds into the pot and is extremely light.
In the past i had an emergency kit that consisted a couple of hexy blocks wrapped in thick foil, some waterproof matches+Striker, an aluminum mug, and 3 longish nails to keep the mug raised off the ground above the lit hexy. I don't think I actually used it in the end (well, apart from the mug that was used constantly), but carried it around for years - i'm sure it would have worked through.
