Just wanted to do a shout-out to Paul at Underground Quilts. I received my Zeppelin 20-degree with baffles yesterday and all I can say is Wow, WoW, WOW!!! Beautiful job! Haven't tried it yet, but I have confidence in the craftsmanship.
Paul's customer service is the BEST--he answers questions and emails promptly, which is a big plus. And he ships it in a large-ish box, out of the stuff sack, so it lofts up right out of the box. If you are thinking of getting an UQ, I highly recommend them.
This weekend I used a Ridgerest and wool blanket for under insulation and it worked okay. And now I have something to compare the new UQ to. Can't wait to try it out!
