So I'm planning my first real hike and hang this coming weekend. Doing an easy three day two night 15 mile hike. The issue comes to the weather. The forecast is saying it will be as low as 28 degrees F with a 70% chance of rain, up to 1.5 inches worth. My current gear is a double layer WBBB, A WB winter Yeti, a WB MamaJama, and a sleeping bag rated down to I believe 40 degrees. What do you guys recommend I try and do as far as setting up the tarp and things?

I am planning on bringing thermal underwear and a couple of shirts to layer up, and possibly a fairly bulky but warm fleece blanket. Do you think a simple space blanket in between the layers of the hammock under my legs will help? Or should I steal my wife's yoga mat to use as a pad? I have a tight budget, but I don't want that to make me freeze all night.

Any tips would be appreciated!
