Quite possibly Steve. Made of pretty sturdy fabric, not the typical rip stop fabric.
Picked it up at the Kopassus base in Jakarta along with a set of unissued Kopassus camo and a set of 1992 TNI-AD OD BDUs.
Still not sure what those webbing straps built into the back are for. I have an alpenflage jump suit with similar straps.
Anyone got an idea of their use?
If anyone is interested in a set (jumpsuit or kopassus etc), drop me a line.
