When the jacket arrived I tried it on to check it out. When I tilted my head forward as if I was setting up for a roll a gap appeared between the back of my neck and the jacket. There was no way that I could tighten the neck enough to prevent the gap. I immediately returned the jacket. The jacket would be OK if you never went upside down.
