These are not genuine JGSDF issue trousers, they are a commercial product.
They feature:
-Button waist with brass zipper fly, made by YBS-Hook and loop adjustable waist tabs
-x2 hook and loop closed thigh cargo pockets
-x2 hook and loop closed slanted rear pockets
-Knee and seat reinforcements
-Hook and loop knee pockets for adding foam knee padding (I am providing two black foam pads that are slightly too large for the pockets, but can easily be trimmed down or replaced as desired)
-Nylon ankle cuff cinches
The only tag is a simple "M" size tag, measurements are as follows:
Waist: 34" (Can be cinched tighter)
Inseam: 30"
