I am trying this again. I am looking for a UQ full 72 or larger 30* to 40* to fit a HH Explorer ULT with zipper option. I had posted before about having an allergy to feathers but it seems from all the information I am getting from people who have the same problem they are using down with no problems. I am going to give it a try. Just need help finding one. Would like to find one from a member rather than buying new until I make sure I can use the down. I for to add that I am working on a tight budget 150.00.
