? Traveling with insulin

My husband is in the military and probably next summer we will be transferring to who knows where (though 99.999% sure it will be in the continental United States). We are currently in southern California so if he gets an East Coast billet that is a lot of driving. Suggestions for long road trips to keep insulin cool? I know about medical coolers but does anyone have any brand suggestions? And any suggestions in the off chance we end up for a night in a place without a fridge? Thanks.

 

These Frio Insulin cooling cases are great....they're also available on Amazon

Only requires water to keep the insulin cool for several days and don't take up much room.
