My EV2 Tent held up fine to the snow and wind. However, because it is a single walled 4 season tent the fabric is not as breathable as other dowble walled tents. I either had to open all the vents which made the tent colder but would allow for better ventilation or I could close some of the vest but the the condensation would build up to the extent that in literally snowed inside the tent when I woke up.
This is a great piece of gear for quick alpine pushes or for one or two night stays at high camp, however, for any other uses I would use another tent.
I also should mention that by no means is this tent comfortable for two people. It worked great for myself and all my gear, but there was no room to spare.
