Both if I could and wanted to. For me there is not one shelter that would cover 4 seasons. The thing I don't like about 2 person is the weight. The thing I don't like about one person is trying to get my gear in it with and do functional activities when its pouring rain. Functional activities include things like cooking, changing clothes, packing my gear into my pack, ect...Hammocks are nice, but I don't pretend to enjoy them in winter - its just too heavy to carry all that extra stuff to make it functional in cold weather, and I like to lay in my bag all toasty warm and cook my breakfast- so that makes it too confining in the winter.
