Hi! I recently bought a N-Visibag blind from Kirkphoto.com Now, even though the principle isn't that difficult (you cover yourself and the camera with it) the practice is another thing... In particular: what are those strange "pockets" inside and outside, on the frontl part, beneath the net? What's their purpose? And also: how can you move/see beneath that thing, without the birs's seeing you? Please, if you have one, or you know what I'm talking about, let me know... Thanks a lot!
