Never used hammock gear 40* incubator underquilt. I bought this in 2013 along with a 0* incubator, a 20* burrow and 40* burrow. I never ended up using this UQ. At that time they didn’t have premium and Econ, they were all premium. This is standard width, length and fill with DWR 850fp. Weight on my scale is 16.3 oz. I would like to trade for a nice, full sized down UQ in the 25-30* range or sell for $200 tyd.9C60A473-4630-49E0-A299-DF28CF8A1A79.jpg65D530B5-B2B9-47FB-BB4B-DB5723C28951.jpegC22592E1-5897-4AEF-9EA6-C59946FF0DC9.jpeg
