Well, I don't have the money for nice down stuff right now so I've been using poncho liners. They make wonderful top and bottom quilts especially since we car camp. However I didn't think they'd cut it for next weekend up in Iron Mountain, MI. Fortunately I was thinking ahead since it's now forecast to be lows in the upper 20's.
Anyway, down to the important stuff. I decide to beef up our top quilts with some fleece. Found some stuff that I believe is 400 wt and made another top quilt to go inside the PLTQ. I've been told that they don't always like to stay together so we're fixing that problem by putting a couple of buttons on the fleece and holes in the PL to keep them together.
Now the million dollar question is if this modification will be enough to stay nice and toasty. Also have some Insul-Bright coming to slide into the PLUQ, not sure if I'll actually have it by next weekend though.
Here's some pics of the mostly finished products.
