The full body ozone bag is one of the easiest methods we've found for using ozone over your body. You just attach the tubing from your ozone generator to the included adapter, zip yourself up in the bag, pull the zippers to your neck and either sit or lie down for the desired time period. Even though your arms do not stick out of the bag, we have personally tested and determined that a single person can use the bag effectively without assistance after practice.
If you have any ozone leakage from the top of the bag, you can either wrap a towel around your shoulders to block it or turn a small fan on your face to blow away the excess.
