As I continue to refine my setup, and look for that weekend that I'm actually free to do more than hang in the backyard, I hung in the backyard last night to make sure all was well.
Temps got down to about 40, but I awoke at 3am with really cold feet, which was unexpected. The only change I had made was tighten the structural ridgeline to increase the sag. I increased the sag as I noticed most hammock pics I'm seeing (shug's, sclittlefield's, WBBB, etc.) have a lot more room between the hammock body and the ridgeline. (I was specifically looking at sclittlefield's bugnet design)
As I lay diagonally, I noticed a pressure ridge down my calves, along the center axis of the hammock. I can only assume this helped reduce the blood flow to my feet. I did notice with the increased sag, it seemed my feet were elevated a bitmore than normal. I'm also beginning to think my hammock is just a bit too short. I made it from 3 yds of material, and the ends are whipped, but I'm 6' tall. The foot-end whipping is WBBB style, the head-end is the DIY henessy style.
I slept in: Fleece sweats, fleece booties, and had my feet tucked into my top quilt. My UQ: Lost River KAQ, which kept my backside warm and toasty.
Maybe I need more insulation in the footbox of my TQ, or maybe I shoved my feet against the bottom so hard that I compressed the insulation? It was an aggravating night as once I gave up, I found the kids had taken over my space, so I was stuck on the sofa.
The real aggravation was that I THOUGHT I was going to be good down below 40 degrees, and was planning a s24o to make sure before I went out for a weekend. Given that I'm super-busy for the next several months, I'm wondering if I'll be ready for spring at all. (or if I should just break down and buy a good topquilt)
