Cap comforter
A capcomforter is a form of woollen military headgear originating in the British Army.
It is a cylinder of knitted wool, similar to a short scarf, that is typically fitted over the head and fashioned into a hat. It can be worn comfortably underneath a Brodie helmet, and is often sewn shut at one or both ends. The cap comforter bears no insignia, and can be easily stowed without being creased.
History
Cap comforters were introduced in the late 19th century as informal working headdress for British soldiers performing manual labour at camp, and as a comfortable undress cap on active service.First World War
Cap comforters were worn during the First World War as a warm alternative to the service dress cap, as the fabric could be pulled low over the ears in the cold winter trenches. Their casual and non-rigid silhouette made them an ideal item for night time trench raids.Second World War
In the Second World War, soldiers in many British and Canadian regiments wore cap comforters during field training and while carrying out manual tasks.Commandos
The British commandos were an international force recruited from across various Allied units, many with distinctive headdresses. As a solution to this lack of uniformity, commando units adopted their own practical headgear. No.1Commando chose the green beret in imitation of the Royal Armoured Corps, whereas No.2 and No.9 adopted the Scottish tam o' shanter. Other units, including No.4Commando, adopted the cap comforter as their headdress, because it had no prior affiliation with a nation or regiment.In autumn 1942, the War Office approved the green beret as the official commando headgear, though the cap comforter continued to be worn, already synonymous with the apparel of the commandos.
