These are what my PT uses, and I LOVED them. I found them here for less than half what my PT would have charged. They stay cold for about 20-30 min, and I LOVE the cold. It doesn't freeze the skin, but is a penetrating cold that really feels good. So far, no leaks. They remain reasonable pliable in the freezer, and mold to various body parts with ease.
