I normally buy a tent that is classified as a 4 season tent because of the added protection. I have found that you get what you pay for when purchasing a tent.
A few years ago, we were planning a winter snow trip and needed a backup tent so I purchased a model called "Extreme" made by a company called ALPS Mountaineering. It is offered in a two, three, or five person version and is a well designed tent with excellent ventilation.
ALPS manufactures this tent in two different fabrics, offering an "expedition" grade for serious use. If you like this tent, the expedition grade
is the one to buy. The standard model uses a lighter weight fabric to keep the weight down and to keep the tent at a lower price point.
What ever you purchase, do yourself a favor and set the tent up at home a few times before you take it out on the road.
BTW, REI has a great return policy on anything you buy from them. You can also rent a tent from them if you live near one of their stores
