    UQ supplement?

    Okay guys I'm pushing my limits as a cold sleeper using my JRB Nest were it may get down to the 20's at night. Question is what type of light weight material would be best to use to keep my bottom side warm?

    A space blanket would work just fine, as well as a CCF pad, either full or partial langth, depending on where the cold is getting you.

    Would it work better directly under me or between the hammock and quilt? Do you think insultex would work also?

    I was thinking my JRB weathershield might give me a few degrees. Also would my down jacket placed in-between hammock and UQ help more than wearing it for upper body insulation?

    I found the JRB weathershield helped but I am reluctant to try to quantify it - no idea how people say things like "weathershield add xx*F"

    IMO, the weathershield reduces the heat loss due to convection [wind] as opposed to the material itself having any real insulating properties.

    Also, the first thing I would suggest is to pitch your tarp in a "winter configuration" - edges as close to ground as possible and ends as closed as possible.

    After that, it is the usual suspects - ccf pad, inflatable pad, fleece liner, insultex, space blanket, a second UQ

    EDIT - just saw down jacket note.....definately place that in there bet hammock and UQ, try to rig it so that neither the jacket nor the UQ are compressed
    Love my JRB BMB

    Thanks for advice tjm. I'll definitely have to pitch my tarp in that configuration. I wonder if reflectix is an option too?

    I've had really great results with Insultex as a top and bottom quilt temp booster. A single or double layer of IX on the outside of your quilt turns a moderate weather quilt into a real scorcher!

    IX on the outside dose such a great job of (nearly) eliminating heat loss from your quilt that the quilt builds up much more heat than normal.

    It would work between you and quilt as well, but in my experience, not nearly as well.

    A nice IX overcover is a great way to turn any three season quilt into a hearty four season quilt - and when it warms again, just leave the IX at home and you're not carrying the extra weight.

    In your experience how much does it boost? Three season to Four would be around 20 degrees? is that correct?

    if so could someone buy a summer underquilt full lenght and expect to be able to reach three season UQ temps? just asking for sake of discussion.

    I used this setup last spring on Blueberry Mountain in Maine (Spring in Maine = The dead of Winter most other places). It snowed 8", and temps were in mid to low 20's overnight.

    Equipment -
    UQ: DIY Climashield (1 layer of 3oz material)
    IX: 1 layer overcover
    UQ-IX 3.jpg

    TQ: DIY Climashield (1 layer of 3oz material)
    IX: 2 layer overcover

    Me? I was toasty warm while everyone else either left at midnight to trek back to the cabin or shivered all night. I did wear decent base layer clothing (fleece pants and shirt). I'm not sure I needed it, but I didn't feel like removing it either.

    I wouldn't call a single layer of 3oz Climashield a 3-Season quilt - more of a two season. So I think the IX did a tremendous job in conjunction with the climashield (personally, I think a multi-component system like this is ideal, offering many options for varying temperatures).
