Balaclava

.A Balaclava is also called a Ski mask

Originally a knitted wool item they are now made of any stretchy material that will keep you warm and make the Balaclava fit snugly to the head and neck

Designed to cover the whole head and neck, exposing only eyes, nose and mouth (most of the time) it's designed for maximum warmth in cold conditions

The name Balaclava comes from the battle of Balaclava which took place in the Crimean war in 1854. They were never actually worn in the war as, despite the need by British troop fighting in the bitter cold, the headgear never arrived in time. Still, the name stuck.

The Balaclava was also known in the 19th century as the Uhlan cap worn by Polish and Prussian soldiers

Syriyka Cap

When trying to find out what this was I went through many thoughts on where to start, a winter cap for some Soviet block army, but this lacked insulation so I had 2nd thoughts, so the mask was for something else perhaps it was for desert sand storms, turns out I was near enough on the mark.

This is Soviet Russian Afghan war Syriyka Cap with Face mask or near enough.

Also known as kepka-afganka its made of study cotton

This cap was first used in Syria hence Syrika Cap and as a detachable wind proof mask to protect the neck and face, probably used along with googles.

Thanks DanR for this cap.
