Belgian army sleeping bag cover/bivi bag MK4 with a damp proof heat retaining backing and a velcro fastened access flap.
Made by Neirynck Confectie, Belgium.
Sleeping bag can be rolled into the hood to create an easily transportable bedroll. I have rolled the bag into the hood to illustrate the fastenings and carry handle. Have also taken a picture of this compressed down further. Will probably go smaller too.
Approx dimensions 190cm long (excluding hood) and 80cm wide. Weight 700g approx.
