Winter Hammock Condensation Issues
Just got back from a trip up to the mountains of Nagano, Japan. Temps in the low 20's to upper teens. There was about 4 feet of snow on the ground. Needed snowshoes just to break a trail to get to where I was going to hang. I took my Smokehouse tarp, my Ti-Goat wood burning stove, and my Clark NX-250. Under the Clark I had a JRB Mt Washington 3 season convertible. I was using a Golite Ultra 20 TQ. I was wearing Wiggys mesh long johns, base layer, with a down jacket and hat. I had wool socks with hot socks over the top. The stove keeps the inside of the Smokehouse at about 65 degrees constant until she burns out after about an hour of its last stoke. Temps drop off sharply after that. I closed the WS on the Clark over me and slept like a baby all night until nature's call at about 6am. When I opened the Clark WS, the interior was covered with mist, and the top of my TQ was really soaked to about my chest.:scared: On the underside of my Smokehouse tarp there was a fine sheen of frozen mist. My question is, should I have left the WS on the Clark open? Was there a problem in having the WS closed inside the closed sides of the Smokehouse, or was my issue with simply my breath in the cold of both enclosures? I would have assumed some passage of vapor through both surfaces. Since I am a noob to all of this (especially cold weather), is this something that just happens? I know Shug uses a type of "bib" to prevent condensation. I have just ordered a Wildernesslogics TQ which has a fleece condensation protector, so this may help? What can I do next time to help avoid this situation? Thanks in advance for your wisdom!
Wondering out loud.........
I was going to fabricate a condensation shield similar to Shugs, but I just had an epiphany:
Take one old wicking T-shirt (or a really cheap one from China Mart). Cut from the hem, up each side (along the underarm seams) to the shoulders. Cut around the front of the arms, across the shoulders, in back of the knit collar hole. Discard the back, or use it as a hankie.
What you should have left is a knit neck hole and the front of the shirt. Through the hem of the shirt slide a section of 1/8" polypropylene tube - the stiff but flexy stuff. Melt a small hole in the center of the hem for a light shock cord to pass through and tie to the poly tubing.
Stick your head through the neck hole. Attach the shock cord to the interior ridgeline and adjust as needed. The tube acts as a batten to give the device some shape to reduce the humid exhaled air from condensing on your TQ.
Yes, I know. Pictures would have been better. I will post some when I construct it.
