Great Cooling Pouch
I bought this for my son's reflux medication and it has worked great for the past 4 flights. The ice stays cold for about 4-6 hours and I haven't had any issues with TSA. I was nervous about how long it would stay cold, so I purchased some additional "ice cubes" from another brand, but I don't think that was really necessary as this does a great job on its own.
