German Cotton Neckerchief. Used / Graded. Olive.
A superb quality genuine-issue triangulated (crikey, that's a big word for me!) piece of material which can be used as a neck / dust / sun protector.
Soak in cold water, wring gently, and use to help keep cool in hot climes.
Can be worn / used in a multitude of ways.
Great in the summer. Great in the winter.
