As most of you would have seen on-line unfortunately allot of SIkh's end up having their Kesh pulled etc when involved in an altercation. Long Kesh also makes it hard to see and protect yourself.
Personally I use two large clips to pin down my Kesh under my Dastaar. This was the Kesh always remain fully intact and away from the face/eyes and can not be easily pulled. Just wanted to share useful this tip with the sangat as their is nothing worse than seeing a Singh being pulled around by their Kesh.
I am sure others have their own ways, however I have found the above to be by far the best for me.
