Hello,
I've been using the same North Face Mountain-24 tent since 1994. It's a beautiful piece of equipment.
The rectangular foot print works well on smaller ledges or when you can only shovel out so much level ground at the end of the day. Also love it's low profile. It's a little on the heavy side though and I'm thinking of going with a sturdy 3 season tent.
Would really like to hear what kinds of tents you guys prefer for steep snow and technical routes, very cold, stormy conditions, wind, dumping snow. What's the lightest tent you would take on steep winter routes above 4000 meters?
