    I'm not used to fighting cold spots at my lower back since mine were more often under the butt or nearer the ends. How flat do you lay in your hammock? In my WBBB, the flat lay combined with snug suspension stretches the suspension enough that it hugs very snugly all along underneath me. It sounds like you have a pocket formed between two snug regions (butt and shoulders), and I dont experience that in my Blackbird.

    Triangle Thingies could be your best friend if this is your problem. I love mine since I can use them to pull my Incubator into a semi-asym alignment. I have the line in the "triangle leg" that connects to my left shoulder and right foot areas tighter than the ones going to my right shoulder and left foot areas. This effectively pulls the quilt slightly off-axis. They also help to pull up instead of just out, which I think would help your problem.

Shock cord on the short ends of the under quilt keep it tight but still stretches with the hammock. Makes sense to me, but no one seems to do this.
    People dont do this generally because of the added weight, added complexity, and because it can make entrance and exit from hammock more difficult depending on the hammock...especially at night. Also, it shouldn't be necesary once you spend enough time fiddling with your suspension. If you were set on trying it, I would use some 3/32 shockcord or even 1.75mm Zing-it mason line instead of grosgrain to eliminate weight. Plus, you could simply push the shockcord to the side for getting in/out the the hammock.

    One size fits all doesn't fit anybody very well.

    As mentioned, get a test dummy, and be prepared to do whatever needs to be done to the suspension to make the quilt do what you need it to, up to and including making a new suspension.

    Maybe I'm not describing it right. I'm talking about adding 5 inch pieces of grosgrain every 16 inches to the sides of the hammock and to the sides of the underquilt. Then just tying the underquilt on to the hammock. I don't think weight could possibly be an issue and there would be no problem getting in and out of the hammock. I'm not saying it's the end-all be-all answer, but it sounds like you were getting the wrong idea. Thanks for the feedback!

    I added "lifters" to my Winter Yeti to assure a tight fit. See it in this video at 3:00 minutes in.

    I'm laying slightly banana-shaped. I've been thinking about this a bit after reading about laying flat, but I'll try to fix one thing at the time. I've felt rested after a night in the hammock, so the sleeping position is no big deal right now, unless it causes other problems. The way you explain it sounds reasonable.

    By hanging the UQ suspension over the ridgeline, I'm trying to get the same effect as the Triangle Thingies (i.e. pulling the UQ ends up rather than outwards).

    I didn't take pictures of the whole setup, but here's a detail of one of the experiments. The thin shock cord from the UQ goes up, through a tiny S-biner (a loop of some kind of cord would work in the same way, I guess) and outwards toward the end of the hammock where they are attached to the end of the hammock (clipped with a biner around the suspension line). The thick shock cords tied to the CRL are from the non-removable bug net of the DD Frontline hammock.



    Since the S-biner want to move outwards, they have to be kept in place with the knot of the bug net cord, or with some cord between them (no big forces here).

    I did have the wrong image in my head. I was thinking something similar to what Shug did, but he used the shockcord like I was recomending.

    I found this video showin what I mean about the tight suspension actually lifting the hammock when empty (at app. 3 min). I don't know if that would solve the issue or not, but it's worth a try since it adds no weight or complexity at all.

    One word for cheap and easy and reversible that may help you easily learn what a seal can do:

    Clothespins.

    A half dozen clothespins used to clip the hem of the UQ to the hammock, holding it up and fastening the edges sothere can be no air-gap, will prove to you whether the seal and air gap are the problem. If you are as warm with the clothespins as without them, the seal they secured was already there.

    I will not forget Knottie's expierience-led advice as a reassurance: Expanding: You are as easily and likely to well figure out by yourself --and only with yourself --how to hang your underquilt as you are to give the back of your head a good haircut with the use of mirrors or turn around to watch your shadow leave a room. ie. Get a friend. Walk around and study the fit with her in the hmmck. Adjust. Learn. Switch places. Listen. Tune. The object is to see that it can get hung so there is no need for those clothespins.

    Paul of AHE has infinitely more experience in this than I do. Looking at hammocks and the furrows, I have my doubts that everyone is as well served by UQs without gaskets -- what are called "draft tubes" on sleeping bags -- but the hmmck world has told me my sense of it is wrong. I freely admit I have not visited even one occupied hammock with an UQ under it except for my own. And I can inspect it as the occupant no better than I can give myself a haircut in a mirror.

    I hang and depend every night on an AHE 2/3 Lost River synth UQ to be insulated underneath. I think I'm better off with the foot end cord up over the hood of the Clark, about where one of Paul's triangle thingies would be on other hammocks. For the head end, I am arresting drift of the shock cord and UQ with keepers, long Velcro ties I keep attached to tie-out loops on the Clark.

    But during the night, the UQ slips down and there's an air gap between the hammock and the UQ. Even though the air there is warm (when I stick my hand down), the hammock gets cool/cold (lower back and thighs). I even tried a piece of string over the ridge line to keep the UQ up, but that didn't help. From what I can see. the lenght of the shock cord is the same (i.e. no slip through the cord lock)

    I'm using a DD Frontline. The UQ is clipped to the whoopie slings as close to the hammock as possible.

    I don't really know where to start adjusting. I was thinking that maybe the sag wasn't enough, but the CRL is as short as possible. Do I have to have more tension on the UQ's suspension (which seems hard to accomplish without the shock cord slipping)?

    Any ideas?
    I just made a DIY hammock and I was having this issue. I do not know much about this UQ, but I fixed my issue by sewing in elastic across the width on either end. The elastic now allows the UQ to cling to my hammock and creates a nice seal.
