Following the end of the Second World War the Canadian Army reviewed its uniforms and introduced a pair of new peaked caps for its troops. One was a lightweight summer cap, whilst the other was a winter cap made of brown serge wool:
This cap has a broad peak to keep the sun off and a brown leather chin strap:
This strap is secured to the cap by a pair of blackened Canadian army buttons, with King’s crowns on them:
Interestingly though, despite the Queen’s crown coming into use from 1952 onwards, this cap wasn’t manufactured until 1954:
From the label we can see that the cap was manufactured by the Buffalo Cap Company and is in a large 7 1/4″ size. These details are repeated on a small label sewn into the joint between crown and peak:
Photos of these caps in service are hard to find, but I have been directed to this one of a parade in the 1950s where the caps can be seen clearly:
These caps actually saw service in Korea but we’re not really suitable as related in Brent Watson’s book “Far Eastern Tour, The Canadian Infantry in Korea 1950-53”:
Helmets were seldom worn on patrol. Instead soldiers wore the equally useless Canadian peaked cap. Designed in late 1950 with the parade square in mind, the cap came in two patterns. The winter version was made of heavy serge and had no provision for ear coverage…Both patterns of peaked cap were incompatible with the hood of the poncho- another item of kit first used by the Canadians in Korea- and undermined its effectiveness. During the battle of Chail-li for example, the peak capped- and poncho clad soldiers of 2RCR were drenched by a vicious 30 minute wind and rainstorm that left them soaked and chilled.
It was quickly recommended that a broad brimmed bush hat, such as used by the British, be introduced to replace the peaked cap in combat.
Tales from the Supply Depot 
For some unknown reason, New Zealand also adopted this headgear around 1954. Officially known as the Cap Battledress (Cap BD) but commonly referred to as the Ski Cap. I can find little written about it or its origins, but from what I can gather it was extremely unpopular, especially with the troops serving in Malaya. The were withdrawn from service in 1964 when coloured berets were universally adopted across the NZ Army.
Very interesting- I hadn’t realised the New Zealanders adopted them as well. A lot of armies seem to have looked into the peaked combat cap at this period, including the British Army, but most seem to have found them unpopular in practice and quickly dropped them!
