Windproof smock

Windproof Smocks are clothing. They usually come with hoods and matching trousers worn as over garments to prevent cold air, and in some cases water, passing though. Windproof smocks are notably used by the likes of commandos and special forces.

Examples
A garment with a similar appearance and colours to the Denison Smock, in lighter-weight denim, the 1942 Pattern Smock, Windproof, was also commonly issued to scouts and snipers in infantry battalions, from 1943, but most notably the SAS/SBS/SOE and Commando squads. It is sometimes incorrectly referred to as the "SAS Windproof". It was not designed much for parachuting, and lacked a crotch flap, having a drawstring hem instead. The most distinctive point of difference between 'Windproofs' and the Denison smock are that the former are hooded. A matching set of over-trousers was produced to complement the smock. Both items were screen printed with colour-fast pigments in a bold splinter design, with colours similar to that of the Denison. Variations of the 'Windproof' have been the basic Special Forces smock until the present, with several alternative colours seen over the years - white (or at least natural cotton) for LRDG's desert use; olive green; black; and, in now very rare later issues of the Smock, Windproof, 1963 Pattern, the Disruptive Pattern Material (DPM) introduced in the late 1960s. The current issue Smock, Windproof is in the latest variation of the DPM design. The camouflage pattern of the "SAS Windproof" was used as the basis of the post World War II Belgian Paratrooper Smock with very similar overtrousers.
