You don't want to carry too much crap with you when you're going on a climbing trip, but you still need to eat. There are several great lightweight camping stoves on the market &mdash one of them is the Primus Eta Pack Lite. It comes with a little carry sack that's about the size of a climbing helmet, and the kit includes pretty much everything you need to make pasta or soup for a couple of people &mdash a burner, an igniter, a pot with a colander top, a wind screen, and a bowl to eat out of. It only weighs 20 ounces, and boiled water in just over two minutes. It's non-stick, so easy to clean, too. I used it to make a couple of meals and I really liked it. It's $115.
