With the windchill into the teens in the Keystone State this evening, I finally had a chance to test my second generation uq. As I am still playing around with different designs/materials, this particular uq is simply made from walmart high loft batting and an emergency blanket tied in. In harrisburg right now it is 19 but feels like 5 with windchill. I've got to say, I am well pleased! Wearing fleece pants, and a sweatshirt I was comfortable. Although their was a intermitent cold spot on my hind quarters, all-in-all I got more than I expected. The question I have for my fellow hangers is: I want to go for down next time, and i am wondering if (given my current success) it is significantly better vs it's difficulty?
