Hi all, I figured I would share my sleepsack self-bondage technique. I've used this method on a darlex sleepsack (with internal sleeves) before and now recently got a canvas sleepsack (with internal sleeves).
Basically I just tie a rope to the zipper pull and to the bedpost. With my darlex sleepsack I had to put a ring around the zipper track to prevent the zipper from going too high and then getting stuck. With this canvas one that is not necessary because I can hold the rather large collar down with my head/neck.
I've tested this a few times with supervision from my girlfriend (who doesn't live with me) and it works super reliably. As for a safety backup or in the event of fire I have a roommate who stays in another bedroom in the apartment. I could always yell to him.
