    A few thoughts after a backyard test

    I tested out my homemade hammock last night. It was a low of 25 degrees with about 10 mph winds.

    Setup:
    homemade Speer style hammock with asym cut
    JRB nest
    McCat Deluxe tarp
    Montbell Super stretch #2 bag used as quilt (rated from 5-20 degrees)
    MEC Northern Lite jacket used as pillow and head cover
    homemade hammock sock

    Clothing:
    Mid Weight bottoms
    swim trunks sans liner
    smartwool long sleeve shirt
    wool socks
    windproof fleece hat

    This was the first night I used the homemade hammock sock and the nest in this hammock. Before I only used the nest with my HH. Bsfore as soon as the temp got to 40 degrees I needed to add a pad for more bottom insulation. I got in the hammock around 1 am last night. The temp was about 34 degrees. I was comfortable with the clothes and gear used. I did not have the hammock sock on yet. I felt comfortable about 10 degrees colder than I did in the HH using the nest. The only reason I can think for this is that I was improperly hanging it on the HH and compressing the insulation. The hammock I am using now probibly has less insulating properties than the HH. The nylon taffeta I think will let more air pass though.

    The thermometer on my ridgeline read 34 degrees. I had my tarp pulled over at this time. I then put my hammock sock on. It was pulled over my head but not tighted around the hammock. This is just a trial version with no closure option. The temp inside approached about 47 degrees. Really comfortable sleeping temp. I woke up around 4am to find a lot of condensation on the sock and my bag. The nylon material I used is not very breathable. The next version will by ripstop and should fix most of this. At this point I pulled the sock down so my head and shoulders where sticking out.

    At about 7am I woke up to snow hitting my face. Unfortunatly the only hammock trees in my backyard are not perpendicluar to to wind. I pulled the sock back over my head and laid there for about 20 minutes. The temp inside the sock went up to around 45 degrees. The temp outside at this point was about 25 degrees.

    At no point did I end up using a pad. I am very happy about that. It is supposed to get down to 15 degrees with 20 mph winds in Cincy tonight. I am planning on testing it again and seeing if I can get a new low. I was suprised to see that I can add about 20 degrees of warmth between the tarp and the sock. I took the ouside temp with a thermometer hanging from the ridgeline but exposed to the wind below the head end of the hammock. I think that with this setup, adding a pad, and wearing my jacket and gloves would get me close to 0.
    Is that too much to ask? Girls with frikkin' lasers on their heads?

    This just gives me more incentive to complete my HH weather shield system. I am thinking a top cover would do a lot to help make sleeping in it at lower temps possible without a pad, which is my ultimate goal I guess. I hate pads in a hammock. I am leaning toward silk right now....

    Hey...where's the pics? How does a hammock sock work? Does it go around the nest/hammock totally , lik a cocoon? How much does it weigh?

    The one I used is made of nylon supplex. Yeah don't buy that stuff. It said WPB, but it is not. It also weighs a lot. The 9' x 80" piece I used weighed in at about 2.5 lbs. I finally found some ripstop at Walmart today. I am going to sew one out of ripstop and try it out soon. I am wondering how much difference it will make. I think being able to close the heas end will make a big difference.

    I just sewed a big tube that was 9 feet long by 80" in circumference. My next version is going to have a draw string closure. I bought enough to make 3 versions. I am going to try the rectangle again, then something more pod shaped to save weight. Unless I put a zipper in, I will still have to leave the open head end the same size.

    My laptop is acting up. I'll try to get some pics up soon. It is basically a big bag that goes over the ridgeline and down below the nest.

    Does it just hang over the ridgeline or is it actually a tube (like a gigantic snakeskin) that goes around everything?

    It is a huge tube made out of 2 pieces of fabric. It goes over the ridgeline in order to keep it out of my face. I have issues with that. It is only open a couple inches on 1 side for the strap to fit in and the other side is open for it to slide over the hammock. I guess you could call it a snake skin for the user.

    ARE you ready to ditch the HH and try a homemade one yet?

    I got some of that heavy supplex, too. It's still in the box it came in...at least it was cheap.
