I picked up on of those Jumbo Sun Shades from Walmart today. The one with the reflective material on one side and white foam on the other. I was testing various configurations, the sun shade is 67" x 27". First I tried it in the hammock, didn't work very well. So I slipped the sun shade between my under quilt and the hammock. when I climbed in the sun shade actually shifted to my diagonal lay. I then through my top quilt on and within 10 minutes I was over heating. I think once my Winter Sock comes in that I'll be able to manage temps well bellow 20*. I'm thinking I may have to test this setup on an overnight hang next week. Now I just have to convince the wife to let me go on an over night trip. Since all you New Englander tend to get cooler temps than we do in Jersey, let me know what you think of this setup.
