The smock was initially worn over the paratrooper's webbing equipment, but under his parachute pack and harness, as its primary purpose was to prevent the wearer's equipment from snagging while emplaned or during a jump. It was equally useful for camouflage and as a windproof garment that provided a method of carrying ammunition or equipment. Contemporary photographs show that airborne troops preferred to wear the smocks under their webbing once they had landed.

 material, allegedly hand-painted with broad, mop like brushes using non-colourfast dyes in broad pea green and dark brown stripes, or "brush-strokes". With use the base colour faded to a sandy buff, and the overlaid shades gained a blended appearance. The colours of the 1st pattern smock were thought to best suit the wearer to the North African and Italian theatres. It had a half length zip fastener made of steel, knitted woollen cuffs, four external pockets that secured with brass snaps (two on the chest and two below the waist), two internal pockets on the chest, and epaulettes that secured with plastic battle dress buttons. The inside of the collar was lined with soft khaki flannel (or in senior officer's smocks, Angora wool). A “beaver tail” fastened beneath the crotch from the back to the front of the smock - which kept it from riding up during a parachute descent. When not used, the tail would hang down behind the wearer's knees, hence the nickname "men with tails", given by the Arabs in North Africa in 1942. The smock was styled as a very loose garment, since it would be worn over Battle Dress

, and thus, hopefully, aiding the wearer's Escape and Evasion chances. As the newly formed Airborne Forces expanded, so the need for smocks grew, meaning that they were by now screen printed for easier production.http://www.kamouflage.net/camouflage/en_00073.php

For use by Airborne troops, the Denison was worn over the battledress and under the webbing, with a sleeveless green denim oversmock being worn over the ensemble to prevent rigging lines snagging in the webbing and causing a 'chute malfunction. This sleeveless smock had a long external zipper (often removed and used to make the half-zip Denisons full zip), a monkey tail that press studded to the outside front of the oversmock and two elasticated open pockets on the lower front which were to hold grenades for use whilst in the air or immediately upon landing. After a successful parachute landing fall, the oversmock was discarded.

2nd Pattern

The 1st Pattern smock design was replaced in 1944 by a second pattern which had buttoning tabs at the cuffs and brass snap fasteners to stow the tail flap on the back of the jacket when not needed. Other detail differences included reduced length and tube shaped rather than tapered sleeves. In order to make it more wind-proof, the tops of woollen socks were often sewn to the cuffs. The half-length zip fastener on this smock was made of brass. The colours of the 2nd pattern also differed from those of the earlier smocks, the base colour varying from a light to a medium olive combination, with overlying brushstrokes of reddish brown and dark olive green. These colours were thought better suited to the North Western European theatre.

Variations

Denisons of either pattern issued to officers had woollen collar linings. By the time of the D-Day airdrops, some officers had had their jackets modified with a full length zip by their personal tailors, since this was not available on the issue item. Wartime photographs show that some other ranks had their smocks serviced the same way by the unit tailor. The zipper was most commonly removed from the 1942 Parachutist's Oversmock, a longer, sleeveless, fully zipped jump-jacket, made of a grey-green denim material that was worn under the parachute harness, but over everything else (including the Denison). This Parachutist's Oversmock also featured a tail flap and its sole intention was to prevent the paratroopers equipment from snagging while emplaned or during a jump. It was to be discarded on landing. The oversmock had capacious elasticated pockets on the skirt, intended as a safer way to carry grenade

s. These pockets were sometimes removed and added to the Denisons as well.
A sniper's variant of the Denison smock is known, in effect an issue smock with a specialized pocket (approximately 10" x 10") added to the left rear in which could be carried food & water, maps, ammunition, and other small equipment. Modifications were done at the unit level and known examples all vary from one sample to the next.

High ranking officers (see photographs) could buy a privately made version of the Denison. Made from a lighter weight gaberdine material, it had a full zip and a drawcord at the waist and a white wool liner to the collar. Frequently seen worn by General Montgomery and General 'Boy' Browning, OC Airborne Troops.
The Royal Marines used a version which had the half zip replaced with buttons and loops for fastening the opening.http://www5b.biglobe.ne.jp/~TANK-GUY/notes/SAS%20figure.html

A waterproof Denison in waxed dark green material was also very rarely found during the War.http://www5b.biglobe.ne.jp/~TANK-GUY/notes/SAS%20figure.html

s, 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.

, 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 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 WW2 Belgian Paratrooper Smock with very similar overtrousers.

SOE Jumpsuit

A camouflaged overall garment in a similar camouflage pattern along with a matching cloth helmet were issued to the SOE and allied agents parachuting into occupied Europe and were discarded shortly after descent. SOE jumpsuits were also issued in white for winter/actic environments.http://www.alliedforum.net/viewtopic.php?f=12&t=301

Post war

The Denison smock (or Smock, camouflage on later garments) remained on inventories in Commonwealth and other militaries after the Second World War, and was popular with troops in Korea. It remained standard combat dress for the Royal Marines

 and the Parachute Regiment until the mid 1970s (see below), and changed little from the wartime issue. A full length brass zip had become standard - with no cloth flap to cover it - and the ever-popular knitted cuffs (deleted on the 2nd Pattern smock, but often imitated by sewing woollen sock tops to the cuffs), were reintroduced. The base colour of the camouflage pattern was now a lighter khaki shade. The "Newey" press studs changed from brass/copper to nickel plated versions.

1959 Pattern

The Denison was significantly modified in the 1959 Pattern. This had a higher hem line, and was much less baggy. This was because wearing it over the personal carrying equipment (but under the parachute harness) while parachuting was no longer the practice. The '59 Pattern retained the full length zipper and knitted wool cuffs, but the flannel lining of the collar was changed from khaki to light green. The most obvious difference to the eye, however, was the change in pattern and colours of the camouflage. The pattern became less random, more defined, with broad, vertical brush-strokes, and greater contrast between the base light khaki and the overprinted tones. The green was much darker than previous versions, and the brown was now chocolate, rather than brick. Where green and brown overlapped, they formed a fourth, darker, olive brown colour.

 and the Parachute Regiment continued to wear the Denison smock, (typically with olive green Trousers, combat, 1960 pattern for field use or "lightweight" trousers in barracks and walking-out) until the late 1970s.

"Although a status symbol in the British Army, the Denison," wrote ex-SAS officer, Barry Gregory, "was windproof but not waterproof and stank after use like a coal-miner's sweat shirt. I used it in extremis as a pillow when sleeping out with sleeping-bag and poncho to keep my head above ground level."


In the UK, the DPM Smock, Parachutist's began to replace the Denison smock (beginning in 1977), to the chagrin of most of their owners, and all the Denisons had disappeared before the Falklands War

 of 1982. The new DPM replacement was not constructed of the Denison’s heavyweight twill, but was instead made from the same cotton material as the ’68-Pattern combat jacket. However, it was cut like the Denison smock, with smaller Newey press-stud (snap) fastened (but now bellowed) pockets, a full length zipper without buttons down the front, the traditional olive green knitted wool cuffs, and a 'crotch flap' on the outside of the back.

The Canadian Airborne Regiment was first issued an olive green replacement for the Denison in the 1950s, and in 1975 a Disruptive Pattern parachute smock entered service, remaining in the inventory until the regiment disbanded in 1995.

 pattern, in which the green and brown brush-strokes were more frequent, but much smaller, on a light greyish green base. Lizard evolved into two main styles: vertical, and horizontal (indicating the general direction of the brushstrokes). Other developments changed the shape of the brushstrokes, using intricate grass-like patterns in the Rhodesian pattern, or palm frond-like sprays in the Indian pattern. South African Denison Smocks (later replaced by the Slangvel) were plain sand coloured.
