Derail away! It still is very pertinent to the conversation. I too are courious about this.

On a side note funny how no matter where we are technologically we still find the basics the best. Wool, down, skin... Anyone see the nat geo a few months ago, the last inset has a picture of a Eskimo with a walrus gut coat. I swear it looks as modern as any high end parka produced today. So it makes sinse that a blanket format is more comfortable in general. It's what we are use to and use everyday.

Talk about derail......
