A traditional Germanic multi-purpose wool toque. The model is tried and true, having been used extensively in WW2, and still serves well when the weather gets cold. Nowadays they make similar "buffs" of polyester, but these are proper wool. Swiss army surplus, very high quality.

Buy two, one for the neck and one over the head.

Made of wool. The color shade and material thickness vary a bit (these are still "thin"), but all toques serve the same purpose.

Condition

Used & repaired when deemed necessary, but overall in nice condition.
