I have hammocked comfortably down to a low of -18 Centigrade.

Having said that, doing so isn't exactly lightweight. I normally go to ground in those temperatures.


But back to the OP - my advice to you is simple. Get *REALISTIC* about how many times you will be out in the winter. Want my advice? rent first. Want my second bit of advice, if you're like most people, spend your 300 on a good lightweight 3 season tent, unless you are mountaineering. it will be lighter, and more comfortable than a true 4 season bombshelter. Now, when you are occasionally going out in 4 seasons, RENT a 4 season tent from rei or a local gear shop.

Me? I have more than one tent. but that way I'm not suffering by carrying a heavy, stuffy 4 season bombshelter that can take a snow load the 95% of the time I don't need it!
