Photo: Then comes the tricky part, passing the head through the neck ring. I have been a bit spoiled during my training sessions, because the Sokol suits I got were typically a bit big for my size and that makes this maneuver a lot easier. When I put on my custom-made suit last week, I had to work a lot harder. You need to make sure that the back side of the suit is as stretched as possible and then you need to tuck in your head while you push the neck ring forward. Tricky at first, but after some practice it&#39;s not so hard.
