I am considering switching to an underquilt. I have never had one before, and I would prefer to start with something of quality so that I have a good experience and don't have to replace it. I am 5'7", and I often curl up to sleep, so I figure a full length quilt is unnecessary. I found this, which seems pretty good, but I haven't found any reviews. I am hoping to be able to hang down to around -10°C, which I have not been able to do with pads. I appreciate any help!
