>>1999993I use pic related MSR whisperlite for winter camping. because of the tube you can turn the isobutane can on its side which is helpful if things are really cold, and i carry a little metal ground pad and windscreen that keeps wind out and head reflecting back in at the pot. pretty good for winter. I used to use it for all seasons actually but recently switched to pocket rocket for 3-season since it's so compact and the tube thing on the whisperlite is kind of annoying to deal with if you don't need it.
