Ok, I just joined and am enjoying this forum a lot! I've gleened a good bit of information. Give me some feedback o the newbie idea.
Today, I hung my ENO ProNest and used my 20 down bag as a Pod. I opened the foot zipper only enough to allow the "foot" carabiner to reach my suspension. All the hammock at that end is inside the bag. I ran the other end through the head opening of the bag. I allowed the bag's zipper to run across the bottom facing the ground.
I then took a length of 3/16 shock cord and attached one end to the "head" carabiner and the other loose end hangs down with a smaller carabiner.
Once I get in, I reach back and attach the hanging shock cord's biner to the zipper at the head end of the bag. When I'm in the hammock, this shock corded carabiner is near the back of my neck, holding the bottom of the sleeping bag taunt and in place without sag. Since at the foot end, all the hammock is inside the bag, there is no air entering at my feel.
Granted today was a sunny 69 but I was warmer than I'd want to be sleeping. I'll be taking it out for a run this coming weekend on an overnight bike trip. So, before I find out the error in my thinking, why does this seems to easy. What am I missing?
