Hello fellow survivors. In the book Winter Wise, the author lists a silk neckerchief in his clothing section. I remember when I was in the Cubs we used to wear them (but I forgot how to roll and tie them). I've read that the cadets and sailors also wear them traditionally. What are all the uses of a neckerchief, especially from a winter survival point of view and from a sailor's tradition and historical point of view? And why silk (which is a bit expensive but feels luxurious) and not another cheaper fabric?

I know the neckerchief used in the Scouts is big enough to serve as a first aid triangular bandage but can you come up with particular usages? And is there a difference in size between a bandanna and a neckerchief?

And where can I find good quality silk neckerchieves?

Thanks
Frankie
