I currently use a Mountain Hardware Skyledge 2.1 Its a really nice two person tent, only a hair over 3lbs and had two good sized vestibules, I took it backpacking in CO last summer for 5 days and it preformed well all around. rained every day was cold and hot and the tent worked well, the material is pretty durable as well, never tore or scratched. this winter I slept in it when it was -7 degrees and it worked great, its a three season but i would have no problems using this tent in the winter with a good bad and pad. Its the best tent I've found for the weight/vestibule size/money. I would get a hilleberg but they are heavier and more expensive.
