I would liek to know how you use your trash bags. If you ask me that seems like a huge pain the A$$, bewteen syran wrap, trash bags, and duct tape to get them to stay on. Idk about you my time isn't free, and I'd rather spend $40 on a neck sweat then $20 oon trash bags, syran wrap, and duct tape, and only take 4 minutes to put on compared to 30. I also turn my calves out at night with the sweats on, much eaiser to work hair throughout the day.
