The story:
We went out to our favorite spot, along the Iowa river in the Hawkeye wildlife management area, around 9pm. The temp was about 25° and was supposed to dip into the teens over night, with a wind developing out of the north.
I hung my hammock so my head pointing west and my feet were pointing east. I closed off both ends of my tarp in "winter mode", paying more attention to sealing off my head end since there was a gentle breeze was out of the NW. From a previous outing I know my DIY underquilt and the ALPS pad can get me down to at least 25°F. The extra pad was a precaution and it was also nice to have under the ALPS pad, since that thing grips like crazy and doesn't budge at all when you are trying to get comfortable. I used the poncho liner as a sleeping bag liner making sure to get a little extra in the foot end.
My feet and lower back felt chilled when I first got settled in, I've experienced this before and don't know what the reason is. I also found out that my balaclava presses on my nose too much to sleep comfortably, plus it felt stuffy to breath with it on, so i left my nose sticking out. I woke up a couple hours later because my face was cold and I just pulled the sleeping bag up over my face, but the rest of me was very warm and comfy.
I woke up again a little before 5 am, not because I was cold, but that north wind had started up and was causing the "doors" to make an annoying flapping noise. I couldn't get back to sleep so I got up, froze my butt off, and battened down the hatches. Thankfully my bed was still warm and it didn't take long to fall back to sleep.
I woke up again at sunrise, this time the wind was much stronger and gusting. the tarp was catching the wind like a sail, pressing against the hammock, and rocking me. It was howling through the trees pretty good, I was just waiting for one of my tie-outs to give. I didn't want to get out of bed though because it sounded cold. The tarp tie-out points held, the braided mason line guy-lines held, and the MSR Groundhog stakes held. I finally got out of bed when I heard my buddy packing up. Both of us wanted to get out of the wind so we packed up and got the heck out of there.
I took a photo before breaking camp...
The overnight low on my temperature gauge was 14°F. There was a bit of frost to knock off on the inside of the tarp. My sleeping bag also felt a little heavier, I'm not sure if breathing into the sleeping bag is such a good idea.
I think I'm set for the cold, just need to tweak a few things... now I just have to figure out how to rig my Kelty for windy conditions.
