The trousers are made of all cotton poplin or rip-stop poplin in olive green army shade 107. They have two front pockets, two hip pockets, and two bellows cargo leg pockets. A small pocket inside the left cargo pocket was designed to carry a survival kit. The trouser legs have draw cords at the bottom.
There are 3 standard patterns
1st Pattern: This had exposed buttons, leg ties in thigh pockets, small loops in crotch for the leg ties and came in Poplin only.
2nd Pattern: This had concealed buttons. The rest was the same as 1st Pattern.
3rd Pattern: This had concealed buttons, no leg ties or loops, and came in Poplin or Rip stop.
The ERDL jackets and trousers were the same as 3rd Pattern Jungle Jackets and Trousers. Some trousers have a slide fastener fly (zipper) others with a 5 buttoned fly. Sizes range from small to extra large. Larger sizes are hard to find.. Rip-stop poplin trousers appear at around 1968, but there are some early 1967 prototypes around. These pants are cool and comfortable, but have a tendency to rip, especially at the knee. Be sure to check for the small inner pocket in the front left hand cargo pocket, this is a sure way to date jungle trousers, since the post war ones didn’t have this feature. Also check the rear trouser pockets. There should be a single button. If there are two then you have a post war copy. Check the drawstring at the bottom of the trousers. This should be a ‘rope’ string as opposed to the modern ‘tape’ string. Accuracy is important for the reenactor, care should be taken to get it right.
