Negative Positive
Title: Not as big as you think
Review: These caps only have a 6" diameter if you lay them out flat. Fill them with ice and water and you would be lucky to cover enough area to ice an elbow. If you plan on doing anything like icing your knees go for at least the 9" pack maybe even the 12". But once they are filled the gasket does a nice job of making sure it doesn't leak.
