The fastest-boiling stove you can buy, the Solo brings water to a bubble in about one and a half minutes. If your goal is to go lighter, that matters, because fast boil times mean lugging fewer gas canisters. An added bonus of this 14.7-ounce stove is that its 1-liter pot/heat exchanger acts as a wind barrier, but you can still lift the pot off the burner to prevent singeing (other systems lock the two together).
