Davis' idea was to use copper rivets to reinforce the points of stress, such as on the pocket corners and at the bottom of the button fly.
The trousers had a button fly and tied at the bottom of the legs.
It may or may not have a concealed button fly front.
The pants were made of a khaki wool-twill, pleated with seven belt loops, two scalloped button flap rear pockets, a button fly and a four-inch military style hem.
Most flies now use a zip, though button flies continue in use.
