Fast and Cold
I store these inside a plastic container in my coaches bag (so they don't pop). Once squeezed, which is not impossible to do, they get cold very quickly with a little shake. It helps when an injury occurs to get it iced quickly. The cold doesn't last for super long - but will last for a while to get started taking care of the injury and until you can get home to ice packs or frozen vegetables :-)
