I purchased these to use in lieu of a sleeping bag. Firstly, these are not thick wool blankets. They are heavy as expected, but I bought 2 blankets to compensate for the lack of thickness. These are quite warm if you wrap yourself properly. I use a light sleeping bag liner to help hold it all together, and I stayed warm and toasty at 35 degree F. I would not use these for anything much colder probably without some additional layers. I plan to take these instead of a sleeping bag for my everest base camp trek also. They will be far more comfortable than a restrictive sleeping bag and keep me warm in the unheated teahouses. As a bonus, wool naturally repels bed bugs, so that will be useful when bunking in remote mountain lodges in Nepal where cleanliness is sometimes questionable.
