Been throwing around the idea of using a 100% virgin wool blanket and nothing else as insulation. Has anyone done this? If so how was it. Dont wanna pay for a top quilt and underquilt. Right now I have USGI MSS and it works great. But is bulky and not really applicable for long hikes. Better for short overnighters. Need something for a long haul. I thought of this wool method because when soaking wet it retains 70% ( if not more ) of its heat, and it is easy to repair and has multiple uses. I always said if a piece of gear does not do 3 or more things, I dont want or need it in my pack.
