This is a sterile poncho designed by CISO (Counter Insurgency Support Office) in Okinawa for the indigenous team members, it is the same overall design as the US version but quite a bit smaller and a dark green nylon that isn’t coated in any way. There was also a poncho liner and sleeping bag made by CISO.
This poncho is owned by SOG collector Derek Struth who has kindly let us use it on the site.
