@dlydailyhope I also like Vetwrap or what they call cohesive bandages. It is stretchy and sticks to itself without sticky adhesive and is waterproof. You would need a lot of it, so wrapping your lower back wouldn't work well, but for smaller areas, it may work. It sticks kind of like Saran Wrap. You can get it at places that sell livestock and horse supplies, and even online suppliers. It's about $3 for a 4-inch-wide roll and you can cut it before sticking it together. If you buy it at a pharmacy, it's expensive and in much smaller rolls. I use it for wrapping my ankle similar to using an Ace bandage.
