Abstract: A trouser construction comprising a shell and a removable liner. The shell has a riser, a pair of legs, opposed slant side pockets, a waist band, a stretchable flank and a skirt sewn to the waist band, and spaced buttons attached to the skirt between the skirt and the waist band. The liner has buttonholes at the waist for receiving the buttons, an outer membrane stratum, and an inner fabric stratum, where the membrane stratum is composed of either an expanded microporous polymer or a hydrophilic polymer.

Abstract: A uniform comprising a shirt and trousers. The shirt has a back body section and split front body sections which cooperate with a yoke that extends across the shoulders from arm to arm and over the shoulders and about the collar between the back body section and front body sections. The front body sections have breast pockets, the tops of which are open and overlapped by free edges of the yoke. An inverted pocket at the back section has a bottom opening defined between the back body section and a free edge of the yoke. Display panels are detachably secured within the shirt pockets such that they can be concealed in or extended from the pockets. The trousers have a pair of side patch pockets. Display panels are detachably secured within the patch pockets such that they can be concealed in or extended from the pockets. When the display panels of both the shirt and trousers are extended, they are available for viewing about a substantially 360-degree periphery. Optionally, the display panels are retroreflective.
