This original vintage 100% wool knickers (kniebundhose) were used by the West German Mountain Troops (Gebirgsjaeger) into the 1970's. It is very heavy-duty and hard-wearing. The color is a very interesting OD green - brown blend.
The knickers feature 2 button closed cargo pockets, 2 slash hip pockets, button closed rear pocket, and a button fly. There are loops/straps sewn horizontally in the waistband that allow the jacket to be attached with the pants. This feature makes it a load bearing suit.
There is a "Velcro" or metallic buckle closure that tightens above the calf.
