Now, I don't really have a specific question here. I've just never done a long hike in winter weather, and the thought of getting caught in a 10degF or below storm is a little scary to me.
I've used my drafty 3-season Eureka tent down into the 20s without problems, but I never was hit with any snow on my short trips. I've also crafted a hammock with an underquilt and such, but it's not set up for anything below 30degF at the moment. I have two options in front of me, I think. Buy some sort of fancy winter weather tent (about a minimum of $250 from what I've seen), or hit the books again and try to upgrade the hammock (much cheaper, but will take a little time).
What do you guys use for winter? And why did you choose it? What would you use instead if you had less money, and what would your dream tent be?
