I must say, I much prefer a Wool blanket.
If im packing light, in the mountains for example, I use a Rab down sleeping bag.
If I'm at a permission, running courses, with a basecamp. Give me a quality wool blanket any day.
Not all blankets are equal.
The Knapp, weave, wool, weight, all play a part. Loose fluffy blankets, trap more heat. Dense tightly woven, or felted, keep the wind out better.
A good option is to use two blankets. One fluffy, on top of you, and a lighter tightly woven one over that to keep out the wind, and stop the process of convection.
The Swiss Army blanket is a wool mix. It looks fabulous, and very traditional. It cant compete with the 100% wool military blanket's.
The Italian Army Officers blanket is absolute quality. As is the Yugoslavian.
Some of the bed civilian ones are..
Whitney
Johnathan Atkinson
Filson
Hainsworth
Hudson Bay point blanket.
The Hudson Bay company blanket, is the creme of the crop.
A good blanket should probably weigh over 4lbs, upwards to 8lb
Everyone has different comfort levels, and that's the beauty of wool blanket's for me, they has a far greater comfort range than a sleeping bag . Also far more versatile, with a magnitude of uses.
Then you get to different types of wool.
Bison.
Musk ox
Quiviut.
Camel
Alpaca.
Merino.
Il stop before I start to ramble on. Yep I do like wool blankets ��
