Just took delivery of a dutch army bivi bag, man it's huge and tough-looking. But I have a question. The entrance is a slit down about 1/3 of the way, with velcro fasteners - easy enough. But the entrance is also lined with a row of press-studs which ar all male. In other words, they cant press together. Obviously, there is another piece of kit which press-dtuds around the entrance, a mosi-net maybe? My question, does anyone know what additional piece of kit attaches here? Is it a mosi-net, or some other clever device?
Cheers.
